This week we learned how to convert from General to Standard form. Both of these forms tell you something about the parabola / equation you are dealing with. General Form: C is the y-intercept A will tell you the scale… Continue Reading →

This week we learned about graphing quadratic equations. The first thing to know, is the parent function: This is the most basic and simple parabola form. Now, lets say you modify the parent function so it looks like: This will… Continue Reading →

This week we learned about the discriminant. The discriminant is the part of the quadratic equation that can help yu determine how many solutions there are to the equation. So here is the quadratic equation: And here is the discriminant:… Continue Reading →

This week we learned about quadratic equations. There are three main ways to solve quadratic equations: 1. Factoring 2. Completing the Square 3. Quadratic Formula Factoring: Factoring quadratics is very similar to factoring polynomials, except there are two solutions instead… Continue Reading →

This week we learned about radicals in expressions, and adding/subtracting them or multiplying/dividing them. Adding: When adding radicals there are a few key things to know: -The only thing that changes is the coefficient. -The index and the radicand must… Continue Reading →

This week we learned about finding the absolute value of numbers. “The absolute value of a real number is defined as the principal square root of the square of a number.” If you wanted to find the absolute value of 5, you… Continue Reading →

This week we learned about infinite geometric series. You can separate geometric series’ into two types, ones that diverge, and ones that converge. If r > 1 or r < -1 then it diverges If 0 < r < 1 or -1 < r < 0 then… Continue Reading →
