Question

What is the equation for the axis of symmetry of the quadratic
function f(x) = 5x2 + 30x - 12?

Answer 1

The equation general form (for up/down parabola) is: x = -b/(2*a) where b is the coefficient of the x terms of the quadratic function and a is the coefficient of the x^2 term.

Crank it out and post what you get.

Answer 2

Is it by any chance, -3?

Answer 3

-3 is not an equation.

Answer 4

Look at the question:

What is the equation for the axis of symmetry? So, not -3 but x = ?

Answer 5

Post what you get.
