Exponential Growth Functions

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 not sure if this gets said much, but I really appreciate that you guys not only post these videos for free, but make them simple and comprehensive too. I also like how the examples used aren't boring as hell, and keep me happy while studying. Kudos.

This website has saved my ass so many times. In our math class we're supposed to teach the class ourselves (a pair teaches a lesson a day) and two morons "taught" this today and gave us all even problems so we can't check anything in the back. I hope I'm doing it right. Thanks :)

Starting with a negative exponent is a great idea. It really makes it clear for the student.

Isaiah 41:10 "Fear not, for I am with you. . . . I will strengthen you, yes, I will help you, I will uphold you with My righteous right hand." God will help! All of us confront fearful situations, and when we do remember that we are children of God and we must claim the promises that belong to us. He gives us His strength and courage. God helps His children. Never be ashamed about your faith, especially in times of fear. Instead put God first in your life and He will uphold you with His 'righteous right hand'
You guys should join me in saying a prayer "Father, I know I cannot escape this world's troubles, But I also know You will strengthen and help me" Amen!
