# Graphing an equation

Plot the graph of:

y= x^2-2x

#### Solution Preview

y = x^2 - 2x = x*(x-2) ...(1)

If y = 0 => x = 0 and x =2

Hence, the given curve intersects x-axis at x = 0 and x = 2.

Differentiate Eqn (1) with respect to x:

dy/dx = 2*x -2 ...

#### Solution Summary

This shows how to graph a given parabolic equation.
