Front

What is a parabola?

Back

A symmetric curve formed by the graph of a quadratic function.

Front

What is the standard form of a quadratic function?

Back

y = ax² + bx + c

Front

What does the 'a' in the quadratic equation y = ax² + bx + c represent?

Back

The coefficient that determines the direction and width of the parabola.

Front

What is the y-intercept of a quadratic function?

Back

The point where the graph intersects the y-axis (x=0).

Front

How do you find the y-intercept of the function y = 2x² + 3x - 5?

Back

Substitute x=0: y = 2(0)² + 3(0) - 5 = -5.
