Question

Which ordered pair is a solution to the equation? y=x3/4

(8, 6)


(−8, 8)


(6, 8)


(−4, 1)

Answer 1

(8,6)

Explanation:

y=x3/4

y=8(3/4)

y=24/4

y=6

when you input 8 for x, you get 6 for y.

Answer 2

Explanation:

y = x3/4 is ambiguous. I will assume that you meant

x^3

y = ---------

4

Then, if x = 8, y = 128 (not a solution)

If x = -8, y = -128 (not a solution)

If x = 6, y = 54 (not a solution)

If x = -4, y = -1/4 (not a solution)]
