f(x)= x^4 find derivative and also slope when x=1 and x = -2
-------
f'(x) = 4x^3
---
f'(1) = 4
f'(-2) = -32

f(x)= x^4 find derivative and also slope when x=1 and x = -2
:
use the power rule for the derivative
:
f'(x) = 4x^3
:
when x=1, the slope is 4(1^3) = 4
:
when x=-2, the slope is 4((-2)^3) = -32
