Find the derivative of f(x) = x
4
+ 5x
f ' (x) = 4x2 + 5
f ' (x) = 4x3 + 5
f ' (x) = 12x3 + 5x
f ' (x) = 4x3
2
Find the derivative of f(x) = 4x
1/
2
+ 2
f ' (x) = 2x1/2
f ' (x) = 8x-1/2
f ' (x) = 2x-1/2
f ' (x) = 8x-1/2 + 2

Find the derivative of f(x) = 7x
-1
f ' (x) = -7x-1
f ' (x) = 7x-2
f ' (x) = -7x-2
f ' (x) = -7x
8
At which x - value(s) is the graph shown not differentiable?
x = 0
x = 0 and x =1
x = -2 and x = 2
x =1
9
Determine the x-value(s), if any, at which f (x) = x
3
+ 6x - 2 has a horizontal tangent.
x = 3
x = 2
x = -2
The graph has no horizontal tangents
