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

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

#1 is linear

Nooo mine is absolute value function. Right?

#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
