Question

how do I determine these?????
Determine whether each of the following equations
defines y as a function of x. (Do not graph.)
27. 3x − 5y = 8

Answer 1

If y is a function of x, there will only be one output. The easiest way to do this is to isolate y and plug in a number for x. If you get something like 2 and -2, or 4 and -4, it isn't a function of y. It cannot correspond with more than one y value.
