Use the following function rule to find f(2.6).

Question

f(x) =
x
2

− 7.25

Write your answer as a decimal or whole number.

f(2.6) =

Answer 1

To find \( f(2.6) \) using the function rule \( f(x) = x^2 - 7.25 \), we first need to calculate \( 2.6^2 \).

Calculating \( 2.6^2 \):

\[ 2.6^2 = 6.76 \]

Now we substitute this value back into the function:

\[ f(2.6) = 6.76 - 7.25 \]

Now, we perform the subtraction:

\[ f(2.6) = 6.76 - 7.25 = -0.49 \]

Thus, the answer is:

\[ f(2.6) = -0.49 \]
