Algebra 2 properties of parabolas worksheet
For y = ax² + bx + c the axis of symmetry is x = -b over 2a, the vertex sits on it, and the y-intercept is c. The sign of a says which way it opens, and the vertex is then the minimum or the maximum, which also fixes the range.

How to do these
Vertex, axis of symmetry, -intercept, and opens up or down:
- Axis: x = 6 over 2, which is 3.
- Vertex: y at x = 3 is 9 - 18 + 5, which is -4.
- Intercept c = 5; a is positive so it opens up.
The answer is Vertex , axis , -intercept , opens up.
Where students go wrong
Losing the minus in -b over 2a. For y = x² - 6x + 5, b is -6, so the axis is at positive 3.
Also called vertex and axis of symmetry, maximum or minimum of a quadratic, range of a parabola or quadratic features.
