Question

Ill Give Medals!!
Given f(x) = x + 2 and g(x) = x2 – 4, find the function (g/f)(x).

Answer 1

hint:

Difference of squares
a^2 - b^2 = (a-b)(a+b)

Answer 2

so you have as @iambatman and @jim_thompson5910 said
you have to simplify this thing: (x+2)/((x+2)*(x-2)) let us know what you get

Answer 3

iambatman, you have g and f mixed up

Answer 4

Oops!

Answer 5

\[\frac{ g(x) }{ f(x) }=\frac{ (x^2-4) }{ (x+2) }\] nice catch jim!

Answer 6

How do i know that excluded value? I got the answer x-2 for the problem. Im just missing the excluded value..Help Pleasee

Answer 7

I actually just figured out the excluded value is -2(: Thanks guys!

Answer 8

you cannot divide by zero

so if the denominator is zero, then x+2 = 0 leads to x = -2 like you got
