Question

Use the following function rule to find f(1.6). f(x) = x 2 − 6.12 Write your answer as a decimal or whole number. f(1.6) =

Answer 1

To find \( f(1.6) \) using the function rule \( f(x) = x^2 - 6.12 \), we will substitute \( 1.6 \) for \( x \) in the function.

\[
f(1.6) = (1.6)^2 - 6.12
\]

First, we calculate \( (1.6)^2 \):

\[
(1.6)^2 = 2.56
\]

Now, we can substitute this value back into the function:

\[
f(1.6) = 2.56 - 6.12
\]

Next, we perform the subtraction:

\[
f(1.6) = 2.56 - 6.12 = -3.56
\]

Thus, the value of \( f(1.6) \) is:

\[
\boxed{-3.56}
\]
