Question

Domain and range? I need some refreshing , what would be the domain of 3y/y+5

Answer 1

\[\frac{3y}{y+5}\]

Answer 2

yes

Answer 3

\[y \ne -5\] so the domain is (-infty, -5) (-5, infty)

To find the range, you have to find the inverse of the function.

Answer 4

So whatever makes it zero right?

Answer 5

Give me a minute to figure this out

Answer 6

And how do the domains of a square root work?

Answer 7

Let's do one thing at a time. Let me find the range of the function first

Answer 8

Sorry sorry , didn't mean to swamp you ha

Answer 9

Okay, I figured it out after much difficulty

Answer 10

To find the inverse, first set the expression equal to x....
