Question

f(a)=-6(a+1)-7
f(4)=
simplify you answer

Answer 1

To find \( f(4) \), we start by substituting \( a = 4 \) into the function \( f(a) = -6(a + 1) - 7 \).

\[
f(4) = -6(4 + 1) - 7
\]

First, calculate \( 4 + 1 \):

\[
4 + 1 = 5
\]

Now substitute this back into the function:

\[
f(4) = -6(5) - 7
\]

Next, calculate \( -6(5) \):

\[
-6(5) = -30
\]

Now substitute back into the equation:

\[
f(4) = -30 - 7
\]

Finally, subtract \( 7 \) from \( -30 \):

\[
f(4) = -37
\]

Thus, the simplified answer is:

\[
\boxed{-37}
\]
