Find f(a-3) when f(×) = -2×-5

Sagot :

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
