Question

Use the following function rule to find f(1). f(x) = – ( 3 ) x − 12 f(1) =

Answer 1

To find \( f(1) \) using the function rule \( f(x) = - (3)x - 12 \), we can substitute \( x = 1 \) into the equation.

\[
f(1) = - (3)(1) - 12
\]

Now, calculate it step-by-step:

1. Calculate \( - (3)(1) \):
\[
- (3 \cdot 1) = -3
\]

2. Then subtract 12:
\[
-3 - 12 = -15
\]

So, \( f(1) = -15 \).

Thus, \( f(1) = -15 \).
