Question

please solve this problem for me. 1. Find the domain of the composite function f∘g. f(x)=x2+2; g(x)=√x−1

Answer 1

is it
\[g(x)=\sqrt{x-1}\]?

Answer 2

if so then the domain of \(f\circ g\) first off cannot be bigger than the domain of \(g\) because you have to do \(g\) first
to find the domain of \(g\) set \(x-1\geq 0\) and solve for \(x\) in one step

Answer 3

that will be your final answer because you can square any number and add two to any number so \(f\) does not matter in this problem

Answer 4

okay so am i supposed to solve g(x)
