You can put this solution on YOUR website! This is the easiest way to graph a simple parabola:
Choose any small numbers, positive or negative, near 0. Put them in the equation.
choose: -2,-1,0,1,2
f(-2)=(-2)^2=4
f(-1)=(-1)^2=1
f(0)=0^2=0
f(1)=1^2=1
f(2)=2^2=4
Plot the points: .
Notice a trend there? The graph will continue like that forever--- it will get larger and larger the higher the x-value you put in. See below:
