Question

How do you graph `y=3x^2`?

Answer 1

Refer Explanation section

Explanation:

Given -

`y=3x^2`

There is no constant term in the function. Hence, it must pass through `(0, 0)` having its vertex there.
Take a few values on either side of `x=0`
Find the corresponding `y`values place them in the form of a table.

Plot the points and join them. You get the curve.
