For some reason I am stumped

[rolltidejw7]

F(x) = (x -1) (X^2 - 4) / (x + 5) (x^2 - 4x +4)

Find Y-int


I set y = zero.

0=(x-1)(x+2)/(x+5)(x-2)

What do I do now?

 

[stapel]

A fraction is zero when its numerator is zero.

Thank you I think I understand.

... provided the denominator is not zero.
