Question

What is f left parenthesis 4 right parenthesis for the function f left parenthesis x right parenthesis equals 7 x plus 8​?

Answer 1

To find \( f(4) \) for the function \( f(x) = 7x + 8 \), you can substitute \( x \) with 4 in the function:

\[
f(4) = 7(4) + 8
\]

Now, calculate:

\[
f(4) = 28 + 8 = 36
\]

So, \( f(4) = 36 \).
