Determine if the equation x - ya = 1 defines y as a function of x.
no. at least one input results in more than one output.
yes. one input results in one output.
no. at least one output results in more than one input.
yes. one output results in one input.

  Yes. One input results in one output.

Step-by-step explanation:

If "A" is not dependent upon x or y, this is a linear equation. Any linear equation in two (or more) variables defines a function.

Yes, this equation defines a function.

__

A function has one output for each input. The appropriate description is the one shown as the Answer.

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

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
