Complete the table for each function

1. f(x)=3x2 -3
2. g(x)= 1/9x2
3. h(x)= -x2

ive tried to do this multiple times and I feel like I keep getting the table wrong which prohibits me from finishing the questions.


I made this makeshift table so anyone can copy and paste it to put the numbers in he table

x| 0 | +1 | +2 | +3 |
y| | | | |

The table is asking you what value the functions (f(x), g(x), and h(x) take when x has a specific value.  The variable y is used as a placeholder for f(x), g(x), or h(x).  For example:
 
f(x) = y = 3x2 - 3
 
When x = 0, just replace the x in f(x) with a zero:
y = f(x=0) = 3*(0)2 - 3 = -3
 
So in the table under x=0, enter -3 for y.
 
When x = 1, y = f(x=1) = 3*(1)2 - 3 = 3 - 3 = 0
When x = 2, y = f(x=2) = 3*(2)2 - 3 = 3*4 - 3 = 12 - 3 = 9
 
So for f(x), the table looks like:
 
x= |  0 | 1 | 2 | 3 |
y= | -3 | 0 | 9 | ? |
 
Can you complete the rest?
