The graph of a quadratic function is called a parabola.
There are 3 forms of quadratic equations.
If A is positive, the parabola opens up or to the right.
If A is negative, it opens downwards or to the left.
All quadratic equations have a vertex, which is the turning point of the graph.
Quadratic graphs are symmetrical across the y-axis, which runs through the axis of symmetry. Formula: x= -b/2a
A quadratic function crosses the y-axis when x=0
The y-intercept always has an x-value of 0.
For a parabola, the y-intercept will be the point(don’t know this one sorry!)
A quadratic function crosses or touches the x-axis once, twice, or never.
