Answer:

x | y

-1 | 2

-0.5 | -0.25

0 | -1

0.5 | -0.25

1 | 2

The graph is attached.

Explanation:

You have the following function:


y=3x^(2)-1

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


y=3(-1)^(2)-1=2

x=-0.5


y=3(-0.5)^(2)-1=-0.25

x=0


y=3(0)^(2)-1=-1

x=0.5


y=3(0.5)^(2)-1=-0.25

x=1


y=3(1)^(2)-1=2

Table:

x | y

-1 | 2

-0.5 | -0.25

0 | -1

0.5 | -0.25

1 | 2

The graph is attached.
