What is the axis of symmetry for a parabola with vertex at (-3, 2)?

Back

The axis of symmetry is the vertical line that passes through the vertex. For the vertex (-3, 2), the axis of symmetry is given by the equation x = -3.

How do you find the y-value of a quadratic function at a specific x-value?

Back

Substitute the x-value into the function and simplify to find the corresponding y-value.

Back

The 'a' value determines the direction of the parabola: if 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

How do you find the y-intercept of a quadratic function?

Back

The y-intercept can be found by evaluating the function at x = 0.
