Question

Hi, can you help me to solve this problem please!

Answer 1

Given,

The function is,

`g(x)=x^2+10x+6`

Taking x = a - 7 then,

`\begin{gathered} g(a-7)=(a-7)^2+10(a-7)+6 \\ =(a^2-14a+49)+10a-70+6 \\ =a^2-14a+10a+49-70+6 \\ =a^2-4a-15 \end{gathered}`

Hence, the function is f(a-7) = a^2-4a-15.
