Quadratics Graphs

Front

What are the x-intercepts of a quadratic graph?

Back

The x-intercepts are the points where the graph crosses the x-axis. For example, x=0 and x=4.

Which point is an example of a y-intercept?

Back

The y-intercept is the point where the graph crosses the y-axis. An example is (0,4).

Front

How do you determine the solutions from a quadratic graph?

Back

The solutions are the x-values where the graph intersects the x-axis. For example, the solutions can be 1 and 3.

How many solutions can a quadratic graph have?

Back

A quadratic graph can have one, two, or no solutions.

Front

What is the vertex of a quadratic graph?

Back

The vertex is the highest or lowest point of the graph, depending on its direction.

Front

What does it mean if a quadratic graph opens upwards?

Back

If a quadratic graph opens upwards, it means the vertex is the lowest point and the solutions are real and can be two or one.

What is the axis of symmetry in a quadratic graph?

Back

The axis of symmetry is a vertical line that divides the graph into two mirror images.

Front

What is the standard form of a quadratic equation?

Back

The standard form is y = ax² + bx + c, where a, b, and c are constants.
