Question

Which answer is the right one according to the image below

Answer 1

To do that, we have to do the following:

`\begin{gathered} t(s(x))=t(x\text{ -}7) \\ =4(x\text{ - }7)^2\text{ - }(x\text{ - }7)+3 \\ \\ \end{gathered}`

So, that would be the equivalent expression, because x is s(x), which is x - 7, so you have to replace every x value with (x - 7)
