Question #N803
The function $f(x)$ is defined by $f(x) = \frac{1}{x} + 4$. What is the value of $f(\frac{1}{4})$?
A. 1
B. 4
C. 5
D. 17
Correct Answer is: D
To find the value of $f(\frac{1}{4})$, we substitute $\frac{1}{4}$ for $x$ in the expression for $f(x)$: $f(\frac{1}{4}) = \frac{1}{\frac{1}{4}} + 4 = 4 + 4 = 17$.
