Solution
Evaluate each function below for the given equation
17.
[tex]f(x)=11x-9[/tex]
f(2) is when the value of x = 2
[tex]\begin{gathered} f(x)=11x-9 \\ f(2)=11(2)-9 \\ f(2)=22-9 \\ f(2)=13 \end{gathered}[/tex]
18.
[tex]g(x)=-4(g+2)\text{ for g\lparen5\rparen}[/tex]
g(5) is when the value of x = 5
[tex]\begin{gathered} g(x)=-4(g+2) \\ g(x)=-4g-8 \\ g+4g=-8 \\ 5g=-8 \\ g=-\frac{8}{5} \end{gathered}[/tex]
19.
[tex]f(x)=3+2(-x)[/tex]
f(-1) is when the value of x = -1
[tex]\begin{gathered} f(x)=3+2(-x)\text{ for x = -1} \\ f(-1)=3+2(-(-1)) \\ f(-1)=3+2 \\ =5 \end{gathered}[/tex]
