Question

y=-3x2 + 18x + 10 what is the axis of symmetry step by step?

Answer 1

Answer and Step-by-step explanation:

$\frac{-b}{2a}$ is the equation to find the axis of symmetry of a quadratic equation.

$y = -3x^{2} + 18x + 10$

-3 = a

18 = b

10 = c

Now we plug the values into the equation.

$\frac{-(18)}{2(-3)} \\\\\\\frac{-18}{-6} \\\\\\3$

The axis of symmetry is on the line x = 3.
