Create an input-output table and graph the function y = 3x squared - 1

x      |      y  

-1      |      2  

-0.5  |   -0.25

0      |      -1    

0.5   |    -0.25

1       |       2  

The graph is attached.

Step-by-step explanation:

You have the following function:

By definition, the input in the independent value and the output is the dependent value.

Therefore, you must give values to x (input values) and substitute them into the function to obtain y for each value (output values).

Then:

x=-1

x=-0.5

x=0

x=0.5

x=1

Table:

x      |      y  

-1      |      2  

-0.5  |   -0.25

0      |      -1    

0.5   |    -0.25

1       |       2  

The graph is attached.

3; 9 is 8 to -4
