I don't understand how to find the domain of a composition function...
f(x)=x^2-1 ; g(x)=x-2 What is the domain of f(g(x))?
Thank you for the opportunity to help you with your question!
domain is the values which x assumes. in your function f(x) it's domain is g(x):
f(g(x))=(x-2)^2-1. Expand to get
solve for x: x^2-4x=-3
Square root both sides to get: x-2=+ or -1
x=3 or 1
