hero (hero):

@PixieDust1, which choice do you believe is correct?

OpenStudy (pixiedust1):

I'm thinking f(x)=x, but I really have no idea

hero (hero):

f(x) = x is correct. If you graph each one, you will see why.

OpenStudy (pixiedust1):

Oh okay! Thanks! How would I graph that?

OpenStudy (pixiedust1):

You mean like just make x= anything, and it should draw a line?

hero (hero):

Graph each function on http://www.desmos.com to observe for yourself how the graphs of the different functions look.

OpenStudy (pixiedust1):

Cool! Thank you :)

OpenStudy (pixiedust1):

Wow! That really makes sense to me. You helped me so much, THANK YOU!!!!
