Question

Use the following function rule to find f(0.21). f(x) = 8.48 + x/0.75 Write your answer as a decimal or whole number. f(0.21) =

Answer 1

To find \( f(0.21) \) using the function rule \( f(x) = 8.48 + \frac{x}{0.75} \), we will substitute \( x = 0.21 \) into the function.

\[
f(0.21) = 8.48 + \frac{0.21}{0.75}
\]

Now, we need to calculate \( \frac{0.21}{0.75} \):

\[
\frac{0.21}{0.75} = 0.28
\]

Next, we substitute this back into the function:

\[
f(0.21) = 8.48 + 0.28 = 8.76
\]

Thus, the value of \( f(0.21) \) is

\[
\boxed{8.76}
\]
