Introduction to Quadratic Functions

Let’s plot the points on the graph that satisfy y=x^2. That is, for each value of x plot (x,x^2).

The integer values are easy to consider. By plotting points at increments of 0.1 we see the form of a parabola.

Every quadratic function of the form y=ax^2+bx+c has this same shape. However, the coefficients a,b and c alter the position and steepness of the parabola.

Use the sliders below to create a variety of parabolas. Try this identify parabola task.
