Question

X

y
-27
0 27
What values complete the table if y = √x?
OA) -9,0,3
OB) -3,0,3
OC) -3,0,9
OD) 9,0,9

Answer 1

• B) - 3, 0, 3

--------------------------

Given x-values in the table.

Use the equation of the function to find the corresponding y-values:

• 
  `y = \sqrt[3]{x}`

When x = - 27:

• 
  `y=\sqrt[3]{-27} =\sqrt[3]{(-3)^3} =-3`

When x = 0:

• 
  `y=\sqrt[3]{0} =0`

When x = 27:

• 
  `y=\sqrt[3]{27} =\sqrt[3]{3^3} =3`

So the missing numbers are: - 3, 0 and 3.

The matching choice is B.
