Question

Which of the following is the equation of the axis of symmetry of the quadratic equation y = 2x2 – 12x + 22?
Answer







x = –3








x = 4








x = –4








x = 3

Answer 1

X=3

Answer 2

By using that formula, along with ax² + bx + c, we have:

a = 2
b = -12
c = 22

x = -(-12)/(2*2)
==> 12/4
==> 3

Hence, the equation of the axis of symmetry is x = 3.
