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.

Here's another tip on where to shade:
If it's a less than sign, you shade below the line
If it's a greater than sign, you shade above the line.

You can use table of values by using intercepts. That way you can understand well when you divide it and when you graph it put the whole cartesian plane .

[nathanielcleveland]

thank you, you helped me understand it better

[Toochi]

some advice for someone who looks up to you greatly and for a future engineer?

[yungpooplord]

I'm doing this in an algebra one class

If you were to add another item, would you need to make the graph 3 dimensional to represent it visually? and if so what would happen when you add a 4th item or a 5th?

WHY TF IS THIS ON MY ALGEBRA 1 TEST?! I HATE ADVANCED MATH

[brian]

hey in 1:48 you talked about at least as less than or equal to, I searched it up and the internet said its greater than or equal to, so am confused

[tmtronin]

this was a really good explanation, thanks!

[cosmicwolf]

Can someone tell me y the 2nd sol. On $25 was less than or equal when nothing in the problem said so

[tmx]

What are the units on the y-axis? How is it legitimate to add dollars and number of products purchased?

[anos_des]

Umm I don't understand the part when he say negative than or equals to? -

[sunzalea]

lost me at 4:02, I dont get it, you said if G is 0 then its S + 0 ≥ 15 im lost

[chrisavila]

I hate math only because Ik the I’m going to forget the easiest formulas when I take the end of the year exam

[amaka]

the video isn't really helpful if you are just currently learning the topic. it assumes you know what he is talking about 😒😒😒

[epicnate]

It doesn’t make any sense, I still don’t get it.

[SabbirHossain-nwzz]

Math is the easiest subject in the world. Do you agree with this?
