Question

Copy and complete the table of values for the relation y equal to 3 x square - 5 x - 7​

Answer 1

x y

0 -7

1 -9

2 -5

3 5

Explanation:

The give function is
`y=3x^2-5x-7`

Assuming the domain is :{0,1,2,3} then we substitute these values into the function and solve for the range.

When x=0,
`y=3(0)^2-5(0)-7=-7`

When x=1,
`y=3(1)^2-5(1)-7=-9`

When x=2,
`y=3(2)^2-5(2)-7=-5`

When x=3,
`y=3(3)^2-5(3)-7=5`

The table then becomes:

x y

0 -7

1 -9

2 -5

3 5
