Question

If f(x) = -5n + 1 and g(x) = -6n + 2, find (f + g)(-2).-182325-25

Answer 1

Determine the expression for (f + g)(x).

`\begin{gathered} (f+g)(x)=f(x)+g(x) \\ =-5n+1-6n+2 \\ =-11n+3 \end{gathered}`

Substitute -2 for n in the equation to obtain the value of (f + g)(-2).

`\begin{gathered} (f+g)(-2)=-11\cdot(-2)+3 \\ =22+3 \\ =25 \end{gathered}`

So answer is 25.
