Complete the table for each function

Question

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|             |           |              |              |        

Answer 1

   x         0       1       2       3

 

 

f(x)      -3       0       9      24

 

g(x)      0       1/9    4/9     1

 

h(x)      0       -1     - 4      -9

 

 

For example, f(0) = 3(0)² -3 = -3

 

g(1) = 1/9 (1)² = 1/9

 

h(3) = -(3)² = -9
