Algebra 1 to Algebra 2 help?

In Geometry, you mostly learn about proofs and how to prove theorems and postulates. You also learn trigonometry which is important in physics when dealing with 2d projectile motion and such. In algebra II, you get to learn more about functions and graphing them. In algebra 1, you covered quadratics functions, which are functions with an x^2. In algebra 2, you get to cover exponential functions, in which the independent variable (x) is the exponent instead of the base (For example: f(x)= 3^x), and also the inverse function of an exponential, which is a logarithm. You learn about compounding interest which uses exponentials to calculate real life situations, such as bacteria growth or radioactive decay. You also learn about transformations, which is how to graph a function by stretching or compressing the base function. You also get to learn more about polynomials that have a degree of higher than a quadratic (ex: x^3 + 2x^2 + 6x + 7) and how to solve for those through different methods of factoring (because you can't just use the quadratic equation.) Hope that helped.

You take geometry between the algebras because algebra 2 is, in general, more... well... general. Instead of just solving simple problems you're asked to generalize what you've learned to more complicated cases. Geometry teaches you to think in this way. That and algebra 2 uses a bit of geometry. Which is crazy when you consider the the ancient Greeks, who used geometry exclusively, didn't even consider algebraic proofs to be valid (algebra being used by the Arabs). Now we embrace both and use them together even (i.e. algebraic geometry and analytic geometry).

Because of Pre-Calculus (Math after Algebra 2).

TRUST ME. GEOMETRY is super important for Pre-Calc especially in understanding Radians. Geometry is pretty easy and you will learn a lot of things.

In Algebra 2 you are to learn things similar but at the same time very different than Algebra 1. For example, how to graph and the formula of elipses, circles, parabola (advanced form), and most important of all Sequences, Series, Probability, Statistics (like game chances and how many combo of numbers in advance form)

I took

Algebra I in the 8th grade,

Geometry in the 9th grade,

Algebra II in the 10th grade.

many years ago.

I have no idea why they did this.

Algebra II is more complicated than Algebra I, it has more details to work with.

bee that's just the way it is, and after Algebra II you go to Pre Cal that uses, you guessed it, Geometry..
