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.

10 years on, and still as helpful as ever! :)
I do K12 and I absolutely love it, but I always get lost in math. Khan Academy helped me so much!!! I probably would have failed Algebra 1 but they helped me get straight As!
Khan Academy is the best thing ever
Helping me. Since I barley pay attention to class since it is so boring. Man you have done such great to the world you deserve a Nobel prize
he sounds like the bee from the mucinex commercials,but i really like the in depth explanations,wayyyy bettr than my teachers.
would f(x) = (Square root of X^2)/2 also be a valid answer for question 6 "write the function rule for each graph"?
thank you so much!
This is really helpful
very helpful ty i learned ALOT believe me
I’m doing work before school I highly suggest anyone do this to get A honor role or if you want to be in honors society. Much love to everyone out there I hope you the best 🙂🫶🏼
X(horizontal) coordinate is always first then the Y(vertical) coordinate...
Can you do a video for different varied fractions for the answer of the function rule. It hard for me to plot fractions although I understood this problem. Also how does the absolute value work here?
yhanks kane very coool
it would have been easier to explain that functions are only one-one mapping and many-one mapping but not one-many and many-many
How do I find the domain and the range for problems 10a and 10b?

just look up and down wise and if the line intersects with another then its not if so it is

How did that test go 8 years ago?
why is it important to know if a relation is a function or not?

It’s pedantics mostly. Youngsters shouldn’t bother with it. Anyone can understand if a function or curve has multiple values or none at a given x and that’s all there is to it.
Not as helpful as I'd hoped. I'm sorry could you explain that a little easier. Its just I am NOT one of those people that get math Easily.
BS at it's finest.
