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. My reasoning in my mind for asking the question that I am asking below is that a function definition follows on definitions such as dictionary.com as follows: Mathematics.
    Also called correspondence, map, mapping, transformation. a relation between two sets in which one element of the second set is assigned to each element of the first set, as the expression y = x 2; operator.
    Also called multiple-value function. a relation between two sets in which two or more elements of the second set are assigned to each element of the first set, as y 2= x 2, which assigns to every x the two values y = + x and y = − x.
    a set of ordered pairs in which none of the first elements of the pairs appears twice.

  2. i need to know the name of the speaker for a math essay on functions pleas help as soon as posible

  3. I have two teachers…. and y’know what, you’re better than both of them! (I think, the one I like is exceptionally good and he used to be a professor in a University)

  4. Dear x,
