Question

find the values of x for which f(x)=e^x is increasing.
a. x>0
b. all real numbers
c. x<0
d. x=0
e. no values
PLEASE HELP

Answer 1

A differentiable function is increasing whenever the first derivative is positive.

For f(x) = e^x, the first derivative is f'(x) = e^x. Now for what x is f'(x) > 0?
