Question #N792
The function $f(x)$ is defined as $f(x) = \frac{x^2 + 1}{x - 3}$. What is the value of $f(4)$?
A. -21
B. -5
C. 17
D. 21
Correct Answer is: D
To find the value of f(4), we substitute 4 for x in the function's definition: $f(4) = \frac{4^2 + 1}{4 - 3} = \frac{16 + 1}{1} = \frac{17}{1} = 17$.
