The axis of symmetry for the graph of the function f(x) =3/4 3x2 bx 4 is x =3/2 . what is the value of b?

The value of b is -9.

Step-by-step explanation:

We are given a equation as:

clearly the graph of this function will be a parabola.

for any quadratic equation of the type

the equation of axis of symmetry is given by:

 , here a=3 and b=b

also we are given axis of symmetry as

that means

any options?
