Reciprocal of a Linear Function Part 1

[TheBarbieGirl012345]

will the horizontal aysmptote always be zero? like for every single reciprical linear function?

[AlRichards314]

@TheBarbieGirl012345 Yes, for the recpirocal to a linear function the horizontal asymptote will always be y = 0.

Dear Al, you must be a teacher. If you're not yet, for the benefit of people, please be. Because I have never seen such a calm, thorough, clear, descriptive MATH teacher before. Your way of explaining EVERY single number, sign, value, ...etc is amazing. I am the kind of student who just can't accept a value unless, algebraically, I know how did it come to that specific step. Thank you. If you could post a video About graphing reciprocal of quadratic functions, would be much appreciated.

can u tell me how did u get the values as x -->2.5 in the X,Y table??????wat keys did u press??????leme noe ASAP

[AlRichards314]

Press 2nd Window (Tablset)

Then I'd press TblStart = -2.5 and delta Tbl = 0.05.

The delta Tbl is the change from one x value to the next.

Then press 2nd Graph to access the Table. You'll notice your table on the calculator isn't as long as the one in the video. That's because I pasted 2 of them together to get the one in the video.

OMG thx so much, this video is amazing!!! i love this video, its very clear and effective. Do u know how i can get the TI 83+? it would help with my hw.

[AlRichards314]

Thanks for the comment. To get the calculator do a serach for TI 83 Plus Emulator.  The tricky part is finding the ROM image of the calculator. Legally people aren't supposed to have this unless they own a real calculator, but you should be able to find it somewhere.
