Answer 1

critical points is when the derivative equals to 0 or is DNE

Answer 2

yes. i found the derivative.

Answer 3

then I = to zero.

Answer 4

so it's -2x-5=0

Answer 5

now how do i fnd the critical points from there?

Answer 6

solve for x

Answer 7

x= 5/-2

Answer 8

that's the critical point :)

Answer 9

no no it's saying it's wrong... :(

Answer 10

am i missing something? like (0,5/-2)

Answer 11

if it asks for the coordinates of the point, give in (x, y) form

Answer 12

thank you :)
