Determine if the following relations represent y as a function of x.

Answers:

Each yes/no answer refers to the question "is this a function?"

Explanation:

The last equation is not a function because of the even exponent over the y term. If you apply the fourth root to both sides, you'll end up with y = |x| and y = -|x| as the two possibilities. For any nonzero x, there are multiple y outputs.

The first three equations are functions because we don't have the same issue as the last equation. All exponents for the y terms are odd. Something like y without an exponent really means y^1.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
