Question

Is the graph of y=2x-5/x+7 a translation of the graph of an inverse variation? Explain.

Answer 1

can an inverse exist for the given function?

Answer 2

Yes

Answer 3

I do not think so.
But if you do, could you enter the inverse of that function?

Answer 4

Oh. I mixed things up, no it cant.

Answer 5

also,
for inverse variation, if
x increases, "y" should decrease and vice-versa..
for this function, that does not seem to be happening..

can we use calculus (derivatives) to explain this?
