Overview

The graph of f '(x) is continuous, positive, and has a relative maximum at x = 0. Which of the following statements must be true? (5 points)

The graph of f is always concave down.

The graph of f is always increasing.

The graph of f has a relative maximum at x = 0.

The graph of f has a relative minimum at x = 0.

Below is the graph of f '(x), the derivative of f(x), and has x-intercepts at x = -3, x = 1, and x = 2 and a relative maximum at x = -1.5 and a relative minimum at x = 1.5. Which of the following statement is false?

Graph of a function that increases from negative infinity to x equals negative 1.5, decreases from x equals negative 1.5 to x equals 1.5, crossing the y axis at y equals 6, and increases from x equals 1.5 to positive infinity with x intercepts at x equals negative 3, 1 and 2. (5 points)

f is concave up from x = -1.5 to x = 1.5.

f has an inflection point at x = 1.5.

f has a relative minimum at x = 2.

All of these are false.

The graph of y = f '(x), the derivative of f(x), is shown below. List the intervals where the graph of f is concave down.

Graph consists of 3 line segments from x equals negative 4 to x equals 4. Graph is decreasing from x equals negative 4 to x equals negative 2, increases from x equals negative 2 to x equals 2 and decreases from x equals 2 to x equals 4. There are x intercepts at x equals negative 4, 0 and 4. (5 points)

Which of the following functions grows the fastest as x grows without bound? (5 points)

f(x) = ex

g(x) = ecosx

h(x) = five halves raised to the x power

They all grow at the same rate.

Compare the growth rate of the functions f(x) = x3 + 1 and g(x) = x2 . (5 points)

If f '(x) is always increasing, which statement about f(x) must be true? (5 points)

f(x) passes through the origin.

f(x) is concave downwards for all x.

f(x) has a relative minimum at x = 0.

f(x) has a point of inflection at x = 0.

f is a differentiable function on the interval [0, 1] and g(x) = f(2x). The table below gives values of f '(x). What is the value of g '(0.1)? (5 points)

Use the graph of f(t) = 2t + 2 on the interval [-1, 4] to write the function F(x), where f of x equals the integral from 1 to x of f of t dt . (5 points)

F(x) = x2 + 3x

F(x) = x2 + 2x - 12

F(x) = x2 + 2x - 3

F(x) = x2 + 4x - 8
