AP Calculus AB questions with worked answers

These 8 questions are printed in full on this page and are drawn across all 8 course units. Nothing here is generated on the fly. Cover the options, solve each one on paper, and only then open the worked answer to compare your method with the one shown.

Question 1: Find the limit of (1 - cos x) / x^2 as x approaches 0.

AP Calculus AB · Limits and Continuity

  1. 1/2
  2. 0
  3. 1
  4. the limit does not exist
Show the worked answer
  1. Direct substitution gives 0/0, so more work is needed.
  2. Apply L'Hospital's rule once: the derivatives give sin x / (2x).
  3. That is still 0/0, so apply it again: cos x / 2.
  4. At x = 0 this equals 1/2.

Answer: 1/2

Question 2: What is the derivative of f(x) = the square root of x, evaluated at x = 9?

AP Calculus AB · Differentiation: Definition and Properties

  1. 1/6
  2. 1/3
  3. 6
  4. 3/2
Show the worked answer
  1. Write the function as x to the power 1/2.
  2. The power rule gives f'(x) = (1/2) x to the power -1/2, which is 1 divided by (2 times the square root of x).
  3. At x = 9 the square root is 3.
  4. So f'(9) = 1 / (2 x 3) = 1/6.

Answer: 1/6

Question 3: If y = (2x + 1)^5, what is dy/dx at x = 0?

AP Calculus AB · Composite, Implicit, and Inverse Differentiation

  1. 10
  2. 5
  3. 2
  4. 80
Show the worked answer
  1. Use the chain rule: bring down the 5, drop the power by one, then multiply by the derivative of the inside.
  2. dy/dx = 5(2x + 1)^4 x 2 = 10(2x + 1)^4.
  3. At x = 0 the inside is 1, and 1 to any power is 1.
  4. So dy/dx = 10.

Answer: 10

Question 4: A particle moves with position s(t) = t^3 - 6t^2 + 9t. At what times is it at rest?

AP Calculus AB · Contextual Applications of Differentiation

  1. t = 1 and t = 3
  2. t = 0 and t = 3
  3. t = 2 only
  4. t = 3 and t = 9
Show the worked answer
  1. At rest means velocity is zero, and velocity is the derivative of position.
  2. v(t) = 3t^2 - 12t + 9.
  3. Factor out 3: 3(t^2 - 4t + 3) = 3(t - 1)(t - 3).
  4. So v = 0 at t = 1 and t = 3.

Answer: t = 1 and t = 3

Question 5: For f(x) = x^3 - 3x^2, where is the local minimum and what is its value?

AP Calculus AB · Analytical Applications of Differentiation

  1. at x = 2, value -4
  2. at x = 0, value 0
  3. at x = 1, value -2
  4. at x = 2, value 4
Show the worked answer
  1. f'(x) = 3x^2 - 6x = 3x(x - 2), so the critical points are x = 0 and x = 2.
  2. f''(x) = 6x - 6. At x = 2 this is 6, which is positive, so the curve bends upward there.
  3. A positive second derivative at a critical point means a local minimum.
  4. f(2) = 8 - 12 = -4.

Answer: at x = 2, value -4

Question 6: Evaluate the integral of 2x + 1 over the square root of x, from x = 1 to x = 4.

AP Calculus AB · Integration and Accumulation of Change

  1. 17
  2. 15
  3. 20
  4. 13
Show the worked answer
  1. Rewrite the second term as x to the power -1/2, whose antiderivative is 2 times the square root of x.
  2. So the antiderivative of the whole thing is x^2 + 2 times the square root of x.
  3. At x = 4: 16 + 2(2) = 20.
  4. At x = 1: 1 + 2(1) = 3. Subtract: 20 - 3 = 17.

Answer: 17

Question 7: Solve dy/dx = 2xy with y(0) = 3, then find y(1) to three decimal places.

AP Calculus AB · Differential Equations

  1. 8.155
  2. 6.000
  3. 3.000
  4. 5.437
Show the worked answer
  1. Separate: dy / y = 2x dx.
  2. Integrating gives ln|y| = x^2 + C, so y = A e^(x^2).
  3. y(0) = 3 means A = 3, so y = 3 e^(x^2).
  4. At x = 1: 3e = 3 x 2.71828 = 8.155.

Answer: 8.155

Question 8: What is the area of the region between y = 2x and y = x^2?

AP Calculus AB · Applications of Integration

  1. 4/3
  2. 8/3
  3. 2
  4. 4
Show the worked answer
  1. Find where the curves meet: 2x = x^2 gives x = 0 and x = 2.
  2. Between those points the line is above the parabola, so integrate 2x - x^2.
  3. The antiderivative is x^2 - x^3 / 3.
  4. At x = 2: 4 - 8/3 = 4/3. At x = 0 it is 0, so the area is 4/3.

Answer: 4/3

How the generated AP Calculus AB sets are created

The 8 questions above are fixed and checked. The generator at the top of the page is different: it writes fresh questions with AI from the course and unit information shown here, then the application checks each one for a complete prompt, four choices, one keyed answer, and an explanation. Generated questions are original practice—not official or released exam questions—and AI can still make mathematical mistakes. Verify a disputed answer with the stated method, your course materials, or the MathGPT solver, and follow the site's academic-integrity guidance.

Which AP Calculus AB units does this test cover?

All eight: Limits and Continuity, Differentiation: Definition and Properties, Composite, Implicit, and Inverse Differentiation, Contextual Applications of Differentiation, Analytical Applications of Differentiation, Integration and Accumulation of Change, Differential Equations, Applications of Integration. Study first: Analytical Applications of Differentiation (15–20%) and Integration and Accumulation of Change (15–20%) tie for the largest published weighting.

What should I check first when I review a missed AP Calculus AB question?

Justification questions want the sign chart, not just its conclusion. Say where f' changes from positive to negative, then name the maximum.

What should I do with a missed question?

Classify the miss as a definition, setup, calculation, interpretation, or timing error. Re-solve it from a blank page, then use the MathGPT tutor for a hint or method check.
