What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

What is the vertex of the parabola represented by the point (4,-4)?

Back

The vertex is (4,-4), which is the point where the parabola changes direction.

Front

How do you find the axis of symmetry for a parabola?

Back

The axis of symmetry can be found using the formula x = -b/(2a) from the quadratic equation y = ax^2 + bx + c.

Front

What is the y-intercept of a parabola?

Back

The y-intercept is the point where the parabola crosses the y-axis, found by evaluating the function at x=0.
