Answer:

A)-18

Step-by-step explanation:

Given a quadratic equation of the form $y=ax^2+bx+c$ , the axis of symmetry is determined by the formula $x=-\frac{b}{2a}$ .

If the axis of symmetry of the equation: $f(x)=3x^2+bx+4$ is 3, then:

a=3, b=?, x=3

$x=-\frac{b}{2a}\\3=-\frac{b}{2*3}\\b=-6X3=-18$

The correct option is A.
