Ah, well how about I graph those and you can tell me which you can identify :-) #1 |dw:1342729299574:dw|

Whoaaaaa, wait. What does this have to do with my question?

I'm going in order though your list of options, the name of the game here is to identify the shape :-)

8. HayleyWhite17

#1 is linear

9. HayleyWhite17

So mine is quadratic?

10. agentx5

#5 |dw:1342729526208:dw|

11. agentx5

And finally... #6 |dw:1342729590894:dw|

12. HayleyWhite17

Nooo mine is absolute value function. Right?

13. agentx5

#1. linear, i.e. f(x) = mx+b #2. rational, i.e. f(x) = 1/x #3. quadratic, i.e. f(x) = ax$$^2$$+bx+c #4. cubic, i.e. f(x) = x$$^3$$ #5. radical, i.e. f(x) = $$\sqrt{\text{x}}$$ #6. absolute value, i.e. f(x) = |x| You are correct and now you have a handy little picture guide :-)

In fact I think the only ones you're really missing from this little picture guide are the ones that involve trig functions, logarithms, and higher polynomials ^_^ Hopefully at the level of math you're at you won't be seeing those just yet, until you get this stuff down. This part is just like memorizing shapes.

Got it @HayleyWhite17 ? ^_^

Yessss thank youu
