Question

use the following function f(x) = 7√(130 - x) f(121) =

Explanation:

Step1: Substitute x=121 into f(x)

$f(121) = 7\sqrt{130 - 121}$

Step2: Calculate inside the square root

$130 - 121 = 9$

Step3: Compute the square root

$\sqrt{9} = 3$

Step4: Multiply by 7

$7 \times 3 = 21$

Answer:
