Question

Which of the following is the equation of the axis of symmetry of the quadratic equation y = 2x2 + 24x + 62?

x = –6

x = 6

x = –10

x = 10

Answer 1

Find the vertex form of the parabala.
Or just find the x coordinate of the vertex.
Don't forget to write is as an equation.
It will be x=something.
Use this:
x=-b/(2a) <---this is the axis of symmetry
for a parabola in this form y=ax^2+bx+c

Answer 2

what is a and what is b?
