The axis of symmetry for the graph of the function f(x)=3x2+bx+4 is x equals three-halves. What is the value of b? −18 −9 9 18

b = -9

Step-by-step explanation:

If we have a function with the form:

The axis of symmetry is equal to:

So, for the function , the value of a is 3 and the value of c is 4. It means that its axis of symmetry is equal to:

Solving for b, we get that:

Additionally, the axis of symmetry is , so replacing x by 3/2, we get that b is equal to:

b= -9
