What does the 'a' value indicate in the vertex form?

Back

The 'a' value indicates 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 from the vertex form?

Back

To find the y-intercept, set x = 0 in the vertex form equation and solve for y.

What is the significance of the vertex in a quadratic graph?

Back

The vertex is the highest or lowest point of the parabola, depending on whether it opens upwards or downwards.

How do you determine the direction of a parabola?

Back

The direction of a parabola is determined by the sign of 'a' in the vertex form. If 'a' > 0, it opens upwards; if 'a' < 0, it opens downwards.
