Since the function f(x) is
Since there is no square root for negative numbers, then
We will solve it by adding 7 to both sides
Then we can choose values of x from 7 and greater
Let x = 7
The 1st ordered pair is (7, 0)
Let x = 11
The 2nd ordered pair is (11, 2)
Let x = 8
The 3rd ordered pair is (8, 1)
Let x = 16
The 4th ordered pair is (16, 3)
The 4 ordered pairs are (7, 0), (8, 1), (11, 2), (16, 3)
