Answer:
[tex]f(a-3)=-2a+1[/tex]Explanation: We are given f(x) and we need to find the f(a-3):
[tex]f(x)=-2x-5[/tex]Therefore f(a-3) would be:
[tex]\begin{gathered} f(x)=-2x-5 \\ \therefore\rightarrow \\ f(a-3)=-2(a-3)-5=-2a+6-5=-2a+1 \\ \therefore\rightarrow \\ f(a-3)=-2a+1 \end{gathered}[/tex]Note! We simply evaluated f(x) for x = a-3
