Question

F(x)=2+x^2 and g(x)=sqrt(x-1) find f(g(x))

Answer 1

\(\bf f(x)=2+x^2\\
g(x)=\color{blue}{\sqrt{x-1}}\\
f(g(x)) = 2+\left(\color{blue}{\sqrt{x-1}}\right)^2 \)

Answer 2

real help is appreciated.

Answer 6

well, so.... \(\bf f(g(x)) = 2+\left(\color{blue}{\sqrt{x-1}}\right)^2\)

Answer 7

anything confusing about it?

Answer 8

\(\bf \left(\sqrt{x-1}\right)^2 \implies \sqrt{(x-1)^2}\)
