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

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

Just set it equal to zero and solve

Where it is zero and undefined.

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

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

Of course, what did you differentiate?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

i did the denominator

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