Lesson goal: For loops and plotting parabolas

Previous: Graph the absolute value | Home | Next: Graph a function

Parabolas are those "U"-shaped functions that have the form of

$y=A(x-B)^2+C$ . Plotting parabolas is a great way to learning how the parameters like

$A$ ,

$B$ and

$C$ effect the look and shape of a parabola. You can learn how to plot parabolas here.

Now you try. Try fixing the `y=` statement and the `pset` statement to plot the variable $x$ on the x-axis and $y$ on the y-axis.

Type your code here:

 
pcls(0)
for x=-100,100 do
  y=
  pset( , )
end

See your results here:

This code will not run. You have to fix the y= statement first to define your parabola (hint: try y=x^2). Next, you have to fix the pset statement to plot

$x$ on the x-axis, and

$y$ on the y-axis. Can you do it?

Now you try. Try fixing the y= statement and the pset statement to plot the variable xx on the x-axis and yy on the y-axis.
