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

  1. thAnks to this…now I know…this is so easy.yet when our teachr discussed it..it seem to complicated ……BIG BIG THANKSTO THIS!!!!!!

  2. Wtf when my teacher explained this I was like wtf how am I supposed to solve she made it so complicated, thx u 4 uploaded this video it was so helpful.i would rate this video ★★★★★if I was able to but I will like it.

  3. I have my math exam tomorrow
    Its 25% of my grade and currently I have a 91 on a ten point grading scale

    I think after my grades are updated I’ll have a 93, but hopefully I wont fail my exam

    So thanks video

  4. we had this during grade 8 but I totally forgot all about it and because school just started we are reviewing past lessons. my teacher makes it really confusing and his grammar makes it a whole lot worse! thank you!! you’re a life saver

  5. Khan academy is the best place to waste time and learn a million things that you never intended to learn and likely miss the details that you were looking for to pass exams in the first place.

  6. I understand why the range is all real numbers, but why is it all real numbers greater than or equal to -5

  7. For the range, is it always bound to the y axis? and domain in the x axis? Or am I just imagining false information that will mislead me?

  8. WHY THE FUCK IS THERE NOTHING ON THIS STUPID WEB THAT EXPLAINS FUNCTIONS WITH 2 VARIABLES. E.g. f(4) – e(.5) with f(x)=3x+1 & e(x)=2 over x. Anyone know? MY EXAM IS TOMORROW AND I WAS NEVER TAUGHT THAT YET ITS ON MY REVISION SHEET

  9. how can you tell if the parabola is upward or downward just by looking at the quadratic expression?

  10. I cannot thank you enough for these videos. They are extremely helpful to me. I need all the help I can get 😀
