Question

Given taht the absolute value of (4x^2 - 16) determine where it is not differntiable?
a) At x = -2
b) f (x) is everywhere differentiable
c) At x = -2 and at x = 2
d) At x = 2
e) At x = 4

Answer 1

btw after this can u pleaseeee help me with anotehr question

Answer 2

find where you have sharp turns

Answer 3

lemme graph it now

Answer 4

just set the inside of | | =0 and solve for x to find where f is not differentiable

Answer 5

so x=2

Answer 6

what about x=-2?

Answer 7

is it both...i grahed it and it has sharp turns at x= 2 adn -2

Answer 8

yes the answer is c

Answer 9

thank u....may u help me w/ anotehr problem
