Question

If y^2 = x^3 + 2 which statement is true?

A) the equation is a function at all values of x

B) the equation is not a function

C) the equation is a function only when x<0

D) the equation is a function only when x>0

Answer 1

wow hard to say

Answer 2

it is certainly a function if \(x>0\) because then if you solve for \(y\) you get
\[y=\sqrt{x^3+2}\] which would represent a function

Answer 3

i guess you could go with that one
