Question
I need to make a table of values and graph the following:

y=3x^2

Can you show me the steps on how to do this?

Answer
Take x = 1, 2, 3, 4, 5, 5, 6, 7, 8, 9, and 10.

Now since there is an x² in there, square each of the above numbers and get, in order,
1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.

Lastly, multiply each of them by 3, in order, and get
3, 12, 27, 48, 75, 108, 147, 192, 243, and 300.

So, with the numbers I used, the final table would look like
x   3x²
1    3
2   12
3   27
4   48
5   75
6  108
7  147
8  192
9  243
10 1000.
