    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.

    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.

    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

      By "really really negative, he means some number like -300, as opposed to some number like -3. By "really really positive" he means some number like 300, as opposed to 3.
