Question

May I have a explanation of how to solve this so that it will be easy for me.

Answer 1

Solution

we are given the function

$\begin{gathered} g(x)=-4x+7 \\ we\text{ want to find }g(7) \end{gathered}$

So to find g(7), we will have to replace all the values of x with 7

$\begin{gathered} g(x)=-4x+7 \\ \\ g(7)=-4(7)+7 \\ \\ g(7)=-28+7 \\ \\ g(7)=-21 \end{gathered}$

The answer is -21
