1.Easy
xyx = −3

Let f(x) = −2x5 − 2x2 + 9x + 4. Find the slope of the graph at x = −3, that is f′(−3).

f(x) = −2x5 − 2x2 + 9x + 4x = −3
f′(−3) =
2.Easy
xyx = 3

Let f(x) = 4x5 − 3x2 − 4x + 1. Find the slope of the graph at x = 3, that is f′(3).

f(x) = 4x5 − 3x2 − 4x + 1x = 3
f′(3) =
3.Medium
xyx = 2

Let f(x) = x·sin(3x), with x in radians. Find f′(2).

f(x) = x·sin(3x)x = 2 rad
f′(2) =
4.Medium
xyx = 1

Let f(x) = x·e2x. Find f′(1).

f(x) = x·e2xx = 1
f′(1) =
5.Hard
xyx = 3

The tangent line to f(x) = 3x2 + x − 3 at x = 3 crosses the y-axis at y = b. Find b.

f(x) = 3x2 + x − 3x = 3
b =
6.Hard
xyx = 1

The tangent line to f(x) = x2 − 4x − 2 at x = 1 crosses the y-axis at y = b. Find b.

f(x) = x2 − 4x − 2x = 1
b =
