1.Easy
xyx = 3

Let f(x) = 4x3 − 6x2 − x − 2. Find the slope of the graph at x = 3, that is f′(3).

f(x) = 4x3 − 6x2 − x − 2x = 3
f′(3) =
2.Easy
xyx = −3

Let f(x) = −5x3 + 5x2 + 3x + 5. Find the slope of the graph at x = −3, that is f′(−3).

f(x) = −5x3 + 5x2 + 3x + 5x = −3
f′(−3) =
3.Medium
xyx = 1

Let f(x) = (4x − 3)4. Find f′(1).

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

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

f(x) = x·sin(x)x = 2 rad
f′(2) =
