(Questions posted below)

Answer 1

I didn't get this one

Answer 2

Oh I see c: You have one of the bubbles selected heh.
1/x is a function, yes.
Passes the horizontal line test, yes.
Yah, one-to-one sounds right.

For question 1 ^

Answer 3

\(\Large\rm f(x)=2x^2-3x+1\)

The leading term is of degree 2, so that tells us the shape of the function.
It's going to be some type of parabola opening upward.

Answer 4

There are a few other things we can do if you want to be a little bit more thorough than that.

Answer 5

So, for number 2, will it look like the U?

Answer 6

It's a polynomial so it `is` a function.
Yes the U shape.
Is the U shape one-to-one?

Answer 7

Doesn't it depend on what test yhur doing?

Answer 8

For one-to-one, we check the horizontal line test, yes?
Any U is going to fail that test.
