Explanation:

Given

`y = x^2 - 3`

Required

The graph of the equation

First, we determine the range of y

`x = -3`

`y = x^2 - 3 \to y = (-3)^2 - 3 = 6`

`(-3,6)`

`x = -2`

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

`(-2,1)`

`x = -1`

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

`(-1,-2)`

`x=0`

`y = 0^2 - 3 = -3`

`(0,-3)`

`x = 1`

`y= 1^2 - 3 = -2`

`(1,-2)`

`x = 2`

`y =2^2 - 3 = 1`

`(2,1)`

`x = 3`

`y = 3^2 - 3 = 6`

`(3,6)`
