The equation given is:
y =x² - 4
To get the ordered pairs, we will simply substitute each x- values into the equation and evaluate
When x =-2
y = (-2)² - 4 = 4 - 4 = 0
The first ordered pair is (-2, 0)
When x = -1
y =(-1)² - 4 = 1 - 4 = -3
The ordered pair is (-1, -3)
When x =0
y = (0)² - 4 = -4
The ordered pair is (0, -4)
When x = 1
y=(1)² - 4 = 1 - 4 = -3
The ordered pair is (1, -3)
When x = 2
y = (2)² - 4 = 4 - 4 = 0
The ordered pair is (2, 0)
