What you'll learn
Each question helps you build key knowledge and skills.
- 1The roots of a quadratic are the x-values where the graph crosses the x-axis, i.e. where y=0.
- 2The turning point (vertex) is the minimum or maximum point of the parabola.
- 3For a symmetrical parabola, the turning point's x-value is exactly midway between the two roots.
- 4A cubic graph y=x^3 has an S-shape and passes through the origin.
