Can anyone help? This is the last assignment of the semester and my grade depends on it, teetering at 59 percent. Please guys!

Answer 1

First, what do you think you can do?

Answer 2

First off, what is domain and range? Tell us @cant_do_math and if you need help... well that's what we're here for! =)

Answer 3

I'm not all that sure how to do this, I skimmed over that part. I'm pretty sure the domain and range would be all real numbers, but I'm not positive.

Answer 4

What happens at x=-1?

Answer 5

Let's explore this and figure it out together, yeah?

Answer 6

Sure, but I'm not sure what to do. You'll have to hold my hand and we can explore the unknown together.

Answer 7

Answer 8

As the direction Kainui was pointing you in, we have to understand our definitions first. In the equation 1/(x+1), substitute x = -1 and tell me what you get.

Answer 9

i'm not too sure, to be honest i blew through that. wouldn't x-1 just make it flipped?

Answer 10

Nono, just remind yourself of basic algebraic equations. You have:
1/(x+1)
Now let x = -1. In other words, in the equation 1/(x+1), remove the x and put a -1 there, then simplify.

Answer 11

so 1/(1-1) would be a zero? sorry, I'm not sure what to do with that :(

Answer 12

it will be 1/0
