Domain and range of a function | Functions and their graphs | 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.

For free. For everyone. Forever. #YouCanLearnAnything

I'm studying for an entrance exam into grad school and I can't even do this shit...

[yep]

9:22 "There's no way to get zero"

Audrey Hepburn calls in the background, "nothing is impossible.."

[tabassumsanjana]

You are a great hope for me everytime I have an exam and no preparation

[ausaneepe]

this videos are my student understand about Domain and Range. thank you

[Vhargon]

This is very helpful and informative, I appreciate your videos immensely. You have a new subscriber. It's a great review for my university math.

[GameOnBeast]

This was amazing! Was able to understand each and every bit of domain and range now. Thanks so much Khan Academy!
And for those peeps who don't understand this, you need to go and learn what functions are first. These are basics you need to master

[kohisnegere]

This was the best explanation I ever searched. Thanks very much

[UltimateWaifuXD]

For question 2, I'm trying understand the logic behind this. If Maria charges 15 dollars minimum that would mean that M(h) = 15  0<= h <1  since she charges 15 dollars until an hour has been reached, right?
