What is a parabola?

Back

A parabola is a symmetrical, U-shaped curve that represents the graph of a quadratic function. It can open upwards or downwards depending on the sign of the leading coefficient.

Back

The 'c' represents the y-intercept of the parabola, which is the point where the graph intersects the y-axis.

How do you find the x-intercepts of a quadratic equation?

Back

To find the x-intercepts, set the quadratic equation equal to zero and solve for x. This can be done by factoring, using the quadratic formula, or completing the square.

Front

What are the zeros of a function?

Back

The zeros of a function are the values of x for which the function equals zero. For a quadratic function, these are the x-intercepts of the parabola.
