Back

y = ax² + bx + c

Front

How do you find the vertex of a parabola in standard form?

Back

Use the formula x = -b/(2a) to find the x-coordinate, then substitute back to find the y-coordinate.

Front

Convert the vertex form y = a(x - h)² + k to standard form.

Back

y = ax² - 2ahx + (ah² + k)

Front

What does the 'a' value in a quadratic equation indicate about the parabola?

Back

The 'a' value indicates the direction of the parabola (upward if a > 0, downward if a < 0) and its width.
