Someone please help me answer this inverse function question.

OpenStudy (anonymous):

OpenStudy (jim_thompson5910):

is this function one-to-one?

OpenStudy (anonymous):

I don't think so.

OpenStudy (jim_thompson5910):

why not?

OpenStudy (anonymous):

because there is multiple x's paired with y's

OpenStudy (jim_thompson5910):

or the fact that you can draw a horizontal line through more than 1 point on the function curve

OpenStudy (jim_thompson5910):

either way, this function isn't one-to-one

OpenStudy (jim_thompson5910):

so because it's not one-to-one, the inverse doesn't exist

@jim_thompson5910 Thank you sir.

OpenStudy (jim_thompson5910):

no problem
