The function given is
[tex]f(x)=-3x+4[/tex]
We are asked to evaluate
[tex]f(x+3)[/tex]
To calculate the function f(x+3), we will have to substitute the value of x with x+3 into the f(x)
[tex]\begin{gathered} f(x)=-3x+4 \\ f(x+3)=-3(x+3)+4 \\ f(x+3)=-3x-9+4 \\ f(x+3)=-3x-5 \end{gathered}[/tex]
Hence,
f(x+3) = -3x-5
