(fog)(x), (fog)(2)

. let f(x) = Vx-4 , g(x) = (x+1)^2, find (f o g)(x) and (f o g)(2)

also

let f(x) = 2x-4, g(x) = x^2+1 find (gof) I got 2x^2 - 15 and was incorrect

Re: (fog)(x), (fog)(2)

Hi;

. let f(x) = Vx-4 , g(x) = (x+1)^2, find (f o g)(x) and (f o g)(2)

I am assuming

let f(x) = 2x-4, g(x) = x^2+1 find (gof) I got 2x^2 - 15 and was incorrect


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

f(x) = √ (sqrt) x-4 sorry
