Answer 1

so... what are we looking for?

Answer 2

it says find (f o g)(-3)

Answer 3

ohhh \(\bf f(x)= 3x+4 \qquad {\color{brown}{ g(x)}}= x^2-5
\\ \quad \\
(f\ of \ g)\to (fog)\to f(\quad {\color{brown}{ g(x)}}\quad )\to 3({\color{brown}{ g(x)}})+4\to 3({\color{brown}{ x^2-5}})+4
\\ \quad \\
\\ \quad \\ \quad \\


(f\ of \ g)({\color{blue}{ -3}})\to f(\quad {\color{brown}{ g(x)}}\quad )({\color{blue}{-3}})\to 3({\color{brown}{ {\color{blue}{ -3}}^2-5}})+4\)

Answer 4

ohhhh okay thank you
