Respuesta :

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
