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

Use the formula x=-b/(2a)
This will be axis of symmetry for a parabola in the form y=ax^2+bx+c.

Answer 2

You to identify a and b.

Answer 3

can you tell me what a is in your equation above.
y=ax^2+bx+c
y=2x^2+24x+c
