Question

For f(x)=1/(x-5) and g(x)= x^2+2, find
A. Find the expression for g(x)
B. Substitute the value of g(x) into the function f(x) in place of x to find the value of f(g(x)).
how would i do this?

Answer 1

A. Find the expression for g(x)

Answer 2

aren't you told \(g(x)=x^2+2\) ?

Answer 3

You plug in g(x) for every x in f(x). :)

Answer 4

Sorry, it should be\[f(g(x))=\frac{ 1 }{ g(x)-5 }\]

Answer 5

Can you substitute x^2 + 2 for g(x) and simplify, @theangelsilver ?

Answer 6

Sorry thank you guys for your help
I've already solved it on my own. and yes
