What is the first step required to finding the intervals over which a function increases?
a. use the first derivative test
b. find f ' (x)
c. find critical numbers
d. determine the sign of f ' (x) at important intervals
Also, plzz
Which of the following is a strictly monotonic function
I. f(x) = x^4 - x^2 +6
II. f(x)= x^3 - x^2 +6
III. f (x) = -x^3 + 3
a. only III
b. II and III
c. only I
d. none of the functions are monotonic
