Question

Use the following function rule to find f(5).

f(x) =
(
–10 +
x
)
2


f(5) =

Answer 1

To find \( f(5) \) using the given function rule \( f(x) = (-10 + x)^2 \), we will substitute \( x = 5 \) into the function.

1. Start with the function:
\[
f(x) = (-10 + x)^2
\]

2. Substitute \( 5 \) for \( x \):
\[
f(5) = (-10 + 5)^2
\]

3. Calculate inside the parentheses:
\[
-10 + 5 = -5
\]

4. Now square the result:
\[
f(5) = (-5)^2 = 25
\]

So, the value of \( f(5) \) is \( \boxed{25} \).
