Answer 1

So we would input \(\large{9}\) where \(\large{x}\) is...

\(\LARGE{f(9)=45}\) so we would divide by \(\large{9}\) from both sides to get the variable \(\large{f}\) by itself....

\(\huge\color{purple}{\frac{f(9)}{9}=\frac{45}{9}}\) in which \(\large{f(9)}\) cancels out with \(\large{9}\) in which we are left with....

\(\huge\color{red}{f=\frac{45}{9}}\) which will give us \(\large{f}\)...and then we would start another step...so what would f be?

Answer 2

F would = 5?
5*9 45

Answer 3

Correct ^^ So now we know that \(\large{f}\) equals \(\large{5}\)....now we have \(\large{x}\) equals \(\large{3}\) so...

\(\huge\color{orange}{5(3)=answer}\)

C.15!
Awesome!
Thank you!!

Answer 5
