Question #N123
The function \(f\) is defined by \(f(x) = 8\sqrt{x}\). For what value of \(x\) does \(f(x) = 48\)?
A. 6
B. 8
C. 36
D. 64
Correct Answer is: C
To solve for x, we set the function equal to 48: $8\sqrt{x} = 48$. Dividing both sides by 8, we get $\sqrt{x} = 6$. Squaring both sides gives us $x = 36$.
