Question

use the following function rule to find f(64).
f(x) = 7√(185 − x)
f(64) =

Explanation:

Step1: Substitute x=64 into the function

$f(64) = 7\sqrt{185 - 64}$

Step2: Calculate the value inside the square root

$185 - 64 = 121$

Step3: Compute the square root

$\sqrt{121} = 11$

Step4: Multiply by the coefficient

$7 \times 11 = 77$

Answer:

77
