Question #N124
The function *f* is defined by *f*(x) = 3*x*<sup>2</sup> - 2. What is the value of *f*(4)?
A. 42
B. 44
C. 46
D. 48
Correct Answer is: C
To find *f*(4), we substitute 4 for *x* in the function's definition: *f*(4) = 3(4)<sup>2</sup> - 2. Simplifying, we get *f*(4) = 3(16) - 2 = 48 - 2 = 46.
