Question

find the critical numbers of this function...
g(y) = (y − 2)/(y^2 − 2y + 4)....I found the derivatives...but not sure the next step

Answer 1

equate the derivate to 0 and see what values you get for y

Answer 2

Just set it equal to zero and solve

Answer 3

for the numberator or denomentor?

Answer 4

huh?

Answer 5

Both.

Answer 6

the whole thing( the derivative)

Answer 7

numerator?...

Answer 8

Where it is zero and undefined.

Answer 9

suppose you got y/(y+1) as the derivative, you equate it to zero meaning
y/(y+1) = 0

Answer 10

For that example. y/(y+1) you would consider y=0 and y=-1. Since you want where it is zero and undefined.

Answer 11

i didnt do it that way..can you show me..all i did was derivative and got a bizarre answers

Answer 13

Of course, what did you differentiate?

Answer 14

if 'a' is the derivative that you found , set it equal to =0
a=0

Answer 15

i did the denominator

Answer 16

honestly i can do fraction thats the only thing i hate in math... haha

Answer 17

*cant
