Can someone help me correct these 2?? Pleaseeee The difference between inverses with linear, quadratic, and polynomial functions is Select one a. Linear and Quadratic Functions have similar steps for finding inverses, while Polynomial inverses are completely different. ((INCORRECT)) b. Polynomial functions are closely related to linear functions versus quadratic functions. c. Quadratic Functions are closely related to Linear Functions and little similarity to Polynomial Functions. d. None. The rules for inverses of functions works the same for linear, quadratic, and polynomial equations.

Use the function: f(x) = x^3 + 2 To determine if the function has an inverse you could: Select one: a. Switch the x and y variables then solve for y in the new equation b. Graph the equation and apply the Horizontal Line Test((INCORRECT)) c. Both A and B d. A only

In this second question, what is up with option d? Isn't that exactly the same as option a? LOL

zepdrix (zepdrix):

To determine if something is a function, we apply vertical line test, ya? So to determine if the inverse is a function, we apply horizontal line test. So yes, you had the right idea on this second question. Horizontal line test will tell us `if` the inverse exists. Switching the x and y will tell us exactly what the inverse is. So I guess either method could be used to determine `if` an inverse exists.

OpenStudy (anonymous):

no theres a slight difference

OpenStudy (anonymous):

so C for the 2nd?

zepdrix (zepdrix):

Yes, I think so :)

zepdrix (zepdrix):

The other question, hmm..

OpenStudy (anonymous):

i know

zepdrix (zepdrix):

The first question is kind of confusing. Linear and Quadratic functions are both types of polynomial functions. They both fall into that group. So they're all very closely related in that sense. A Quadratic function won't have an inverse under normal circumstances because it fails the horizontal line test. I'm not really sure what they're looking for here :[ If I had to guess, they probably want you to choose d, d is pretty much saying, use the same approach for finding inverses regardless of what type of polynomial it is, which is true.

zepdrix (zepdrix):

Is this an online thing? Do you get like a second try or something? :)

OpenStudy (anonymous):

yeah i do

zepdrix (zepdrix):

Ahh I hope we don't blow it then XD haha

OpenStudy (anonymous):

ill try d its okay

OpenStudy (anonymous):

Got them right thanks so much!!!!

OpenStudy (anonymous):

Can you help me with some more questions? @zepdrix

zepdrix (zepdrix):

Got em right? :) oo nice

OpenStudy (anonymous):

Haha thanks but do you mind helping or not?

zepdrix (zepdrix):

Oh sure :) Sorry I'm doing some stuff right now. You can post them, I'll try to respond when I can. Or are you on a timer?

OpenStudy (anonymous):

okay great and no im not
