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

ok... for a quadratic

\[ax^2 + bx + c\]

the axis of symmetry is

\[x = \frac{-b}{2a}\]

so in your question b = 24 and a = 2

so just calculate it

Answer 2

x = -6

Answer 3

thats it... to easy
