Question

Use the following function rule to find f(9.49). f(x) = 9.49 x − 0.18 Write your answer as a decimal or whole number. f(9.49) =

Answer 1

To find \( f(9.49) \) using the function rule \( f(x) = 9.49x - 0.18 \), we will substitute \( x \) with \( 9.49 \):

\[
f(9.49) = 9.49 \times 9.49 - 0.18
\]

First, we calculate \( 9.49 \times 9.49 \):

\[
9.49 \times 9.49 = 90.4001
\]

Now we subtract \( 0.18 \):

\[
f(9.49) = 90.4001 - 0.18 = 90.2201
\]

Therefore,

\[
f(9.49) \approx 90.22
\]

So the final answer is:

\[
\boxed{90.22}
\]
