f(4) is function notation that means the value of y when x = 4.
Replace x with 4 in the expression and evaluate the right side.
f(x) = 3x - 15
f(4) = 3(4) - 15
f(4) = 12 - 15
f(4) = -3

hi
f(4) means x=4
As in question it is written that
3x- 15

3 (4) - 15
= 12 - 15
= -3
Therefore the answer is option D.
