Question
If $(f \circ g)(x)=x^{2}-6 x+8$ and $g(x)=x-3,$ which expression could represent $f(x) ?$$$\begin{array}{llll}{\text { F. } x-4} & {\text { G. } x-1} & {\text { H. } x^{2}-1} & {\text { J. } x^{2}-6 x+5}\end{array}$$
Step 1
The composition of functions $(f \circ g)(x)$ means that we substitute $g(x)$ into $f(x)$. Show more…
