Question

Which of the following is a function? y = \pm \sqrt{\frac{x-5}{3x-1}} y = \sqrt{x+6} None of those are functions. 3x^2 + y^2 = 8 All of those are functions.

          Which of the following is a function?
y = \pm \sqrt{\frac{x-5}{3x-1}}
y = \sqrt{x+6}
None of those are functions.
3x^2 + y^2 = 8
All of those are functions.

Which of the following is a function?
y = ±√((x-5)/(3x-1))
y = √(x+6)
None of those are functions.
3x^2 + y^2 = 8
All of those are functions.
