find the axis of symmetry of the graph of the function f(x)=2x^2-12x+19

OpenStudy (jaredstone4):

Formula for the axis of symmetry is: x = -b / 2a So, in your function, a = 2 b = -12 and c = 19 Just sub the values into the formula and solve.

@jaredstone4 so x=3?

OpenStudy (jaredstone4):

Yup, you got it!
