Polynomial end behavior | Polynomial and rational functions | Algebra II | Khan Academy

Missed the previous lesson?

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

swear to god khan academy is better than any teacher I have

[idontcaregoodbye]

i love how he actually explains the reasoning behind things instead of just explaining how to answer a question. it makes it so much easier to understand and grasp

[AarronAndersonPhotography]

This literally saved me for a quiz.... all my confusion (before i got here) was about the odd or even mess....

[ShotBySukh]

I learned a 2-hour lecture in 8 mins and I had fun learning math for the first time too! YOU THE REAL MVP!

[andygarcia]

really really really really really positive

[SGashesNetwork]

This actually was really really really really helpful! :)

[wilsonwayne]

For some reason this guy's voice makes everything easy to understand

[SarinaNayeb]

please do a video on multiplicity and how to know if graph is touching, crossing, and/or turning at the x intercept.

[magicmike]

I think im going to start making math videos. Since I want to tutor at my college, I think making math videos will prepare me for tutoring. Also, I think I can explain "end behavior" really clear. Also, behavior near a zero is awesome too!

[frankyb]

Sal khan is and will be forever the best human

[OmarElkomey-hh]

You do not know how this lesson help me very much. My words can't describe my happy behavior when I listen to this video.

[yohannanayakkara]

explains it better than any other teacher

[LilBlizzardBlizzy]

hol up wtf you got against the color brown!

[kaeleppcohen]

The degree of the polynomial minus 1 is the amount of times your pencil needs to change direction while drawing the curves of the graph. Even works for degree of 1 since it's a straight line.

[snoopdawg]

you’re literally my teacher during this online shij

[kanhaiyakapoor]

Really really really really great video

[REPSOLHONDARR]

to the people that are confused dont worry about the middle part it all about the end part of the graph going up and down also remember the even number and odd number go versa like M to W


also people like me who gotta take these courses to get accepted to civil engineering all these you can put on the computer and it shows it for you its very less complicated but its very important to know all the basics in the back of your head also memorize them they sure come in handy

[enytidbit]

I've been watching videos all morning cuz I have a test on polynomial and we're just confusing me even more. This cleared things up, so thank you so much♡

[nancysoto]

Completely agree! It's just explained way better!

[wirewolf]

What do you mean when you mean "really really negative and really really positive?
