1What is the derivative of f(x) = x^3?
A.f'(x) = 3x^2
B.f'(x) = x^2
C.f'(x) = 3x
D.f'(x) = x^3/3
Explanation: Using the power rule, d/dx[x^n] = n x^(n-1), so f'(x) = 3x^2.
2What is the derivative of f(x) = 5x^2 + 3x - 7?
A.f'(x) = 10x + 3
B.f'(x) = 5x + 3
C.f'(x) = 10x^2 + 3x
D.f'(x) = 10x - 7
Explanation: Differentiating term by term: d/dx[5x^2] = 10x, d/dx[3x] = 3, d/dx[-7] = 0, giving f'(x) = 10x + 3.
3What condition typically indicates a local extremum (maximum or minimum) of a differentiable function f at x0?
A.f'(x0) = 0, with a sign change in f' around x0
B.f(x0) = 0 only
C.f''(x0) is always positive
D.f'(x0) is undefined
Explanation: A necessary condition for a local extremum at an interior point is f'(x0) = 0; confirming it is an actual extremum (not a saddle/inflection) typically requires checking that f' changes sign around x0, or using the second derivative test.
4For f(x) = x^2 - 4x + 3, at what x-value does f have its vertex (extremum)?
A.x = 2
B.x = 4
C.x = -2
D.x = 0
Explanation: f'(x) = 2x - 4. Setting f'(x) = 0: 2x - 4 = 0, so x = 2, which is the location of the parabola's minimum.
5What does the second derivative test indicate if f'(x0) = 0 and f''(x0) > 0?
A.x0 is a local minimum
B.x0 is a local maximum
C.x0 is definitely not an extremum
D.f is undefined at x0
Explanation: When f'(x0) = 0 and f''(x0) > 0, the function is locally concave up at x0, indicating a local minimum.
6What is a point of inflection (Wendepunkt) of a function?
A.A point where the concavity of the function changes (f'' changes sign)
B.A point where f(x) = 0 always
C.A point where the function is undefined
D.A point where the first derivative is always zero
Explanation: An inflection point occurs where the function's concavity switches from concave up to concave down (or vice versa), typically where f''(x) = 0 and changes sign.
7What is ∫ x^2 dx (the indefinite integral)?
A.(x^3)/3 + C
B.2x + C
C.x^3 + C
D.(x^2)/2 + C
Explanation: Using the power rule for integration, ∫x^n dx = x^(n+1)/(n+1) + C, so ∫x^2 dx = x^3/3 + C.
8What does the definite integral ∫[a to b] f(x) dx represent geometrically (for f(x) ≥ 0 on [a,b])?
A.The area under the curve f(x) between x = a and x = b
B.The slope of f(x) at x = a
C.The value of f(x) at x = b only
D.The derivative of f(x) at the midpoint of [a,b]
Explanation: For a non-negative function on [a,b], the definite integral represents the area enclosed between the curve and the x-axis over that interval.
9Evaluate ∫[0 to 2] x dx.
A.2
B.4
C.1
D.0
Explanation: ∫x dx = x^2/2. Evaluating from 0 to 2: (2^2/2) - (0^2/2) = 2 - 0 = 2.
10What does the Fundamental Theorem of Calculus connect?
A.Differentiation and integration as inverse operations
B.Only two unrelated arithmetic operations
C.Probability and statistics
D.Vectors and matrices
Explanation: The Fundamental Theorem of Calculus establishes that differentiation and integration are inverse processes: the derivative of an integral function returns the original integrand.
