Question

F(x)=-17x+2 and g(x)=x^2+1 find f(-7) + g(-7)

Answer 1

171

Step-by-step explanation:

Given f(x) and g(x) defined below:

`\begin{gathered} f\mleft(x\mright)=-17x+2 \\ g\mleft(x\mright)=x^2+1 \end{gathered}`

To find the value of f(-7) + g(-7)​, substitute -7 for x in both functions:

`\begin{gathered} f\mleft(-7\mright)=-17(-7)+2=121 \\ g\mleft(-7\mright)=(-7)^2+1=50 \\ \implies f\mleft(-7\mright)+g\mleft(-7\mright)​ \\ =121+50 \\ =171 \end{gathered}`
