y= √x - 8
Replace each value of x and solve for y
x= 100
y= √100 - 8 = 10-8 = 2
x= 64
y= √64-8 = 8 - 8 = 0
x= 9
y= √9 - 8 = 3 - 8 = -5
x= 36
y=√36 - 8 = 6-8= -2
x= 25
y= √25- 8 = 5 - 8 = -3
For the last values, replace y and solve for x
y=-8
-8= √x - 8
-8+8 = √x
0= √x
x= 0^2
x=0
y=1
1=√x-8
1+8= √x
9 = √x
9^2 = x
x= 81
