Question

Which of the following is the equation of the axis of symmetry of the quadratic equation y = 2(x – 4)^2 + 7?

Answer 1

that equation tells us alot about the grap itself. when a graph is not a the origin, we write notes to tell us where we got it. (x-4) means that we moved it by (-4) from its spot to get a look at it from the origin.

so its axis of symmetry is at x=4
