# What is a parabola? What are the key features of a parabola?

Plot a quadratic equation, what do you see?

We see a parabola :) The graph of a quadratic function is a U-shaped curve called a parabola

Do you notice vertex?

If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.

The parabola is symmetric with a vertical line drawn through the vertex, called the axis of symmetry.

The x intercepts represent the zeros, or roots, of the quadratic function, the values of x at which y = 0
