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

Remember that the axis of symetry is x=value of how far it is from the origin

also remember that the vertex formula is -b/(2a) so
a=3
3/2=-b/(2(3))
3/2=-b/(6)
mutiply both sides by 6
18/2=-b
9=-b
multily both sides by -1
-9=b

so the equation is
f(x)=3x^2-9x+4

b=-9
