f(x) 1-x^(2/3) [-8,8]?

Question

f(x) 1-x^(2/3) [-8,8] whats the ab max and min ?

Answer 1

at x=0, f(x) = 1, that's your max.
as x increases or decreases away from 0, x^(2/3) increases, so f(x) decreases, and your mins are at (-8,-3) and (8,-3). The even exponent on x gives it symmetry around the y axis.
