Question

Use the following function rule to find f(–9.13). f(x) = –5.09 − x Write your answer as a decimal or whole number. f(–9.13) =

Answer 1

To find \( f(-9.13) \) using the function rule \( f(x) = -5.09 - x \), we substitute \( -9.13 \) for \( x \) in the function.

\[
f(-9.13) = -5.09 - (-9.13)
\]

This simplifies to:

\[
f(-9.13) = -5.09 + 9.13
\]

Now, we calculate \( -5.09 + 9.13 \):

\[
-5.09 + 9.13 = 4.04
\]

Therefore,

\[
f(-9.13) = 4.04
\]

The final answer is:

\[
\boxed{4.04}
\]
