Question

How do you graph `y= 2x^2`?

Answer 1

You can make a table where you have X values (any values you want), and you have to find Y values.

For example:

f(0) = 0 T(X,Y) ----> (0,0)
f(1) = 2 T(X,Y) ----> T(1,2)
...

X= 0, -1, 1, 2, -2, ...
Y= ?

Then you put those results in graph and here is the final product:
