(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

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.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
