Front

What does the coefficient 'a' indicate about the parabola?

Back

If 'a' is positive, the parabola opens up; if 'a' is negative, it opens down.

Front

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

Back

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

Front

What is the y-intercept of a quadratic function?

Back

The y-intercept is the point where the graph crosses the y-axis, found by evaluating f(0).

Front
