We will give the basic properties of exponents and illustrate some of the common mistakes students make in working with exponents. We will illustrate these concepts with a couple of quick examples Lines — In this section we will discuss graphing lines.
We define solutions for equations and inequalities and solution sets. Solving Equations and Inequalities - In this chapter we will look at one of the most important topics of the class. Instructional Implications Review the concept of absolute value and how it is written.
Collectively these are often called transformations and if we understand them they can often be used to allow us to quickly graph some fairly complicated functions. One other thing to think about as we complete Example Rational Inequalities — We continue solving inequalities in this section.
While there is some review of exponents, factoring and graphing it is assumed that not a lot of review will be needed to remind you how these topics work. Negative Slopes are Tricky. Here are a couple of warnings to my students who may be here to get a copy of what happened on a day that you missed.
Repeat the process if you'd like to plot a 3rd point. We have written an absolute value inequality that models this relationship. Solutions and Solution Sets — In this section we introduce some of the basic notation and ideas involved in solving equations and inequalities. We will discuss solving linear and quadratic equations as well as applications.
In other words, the dog can only be at a distance less than or equal to the length of the leash. Writing inequalities algebra Absolute value inequalities Video transcript A carpenter is using a lathe to shape the final leg of a hand-crafted table.
A difference is described between two values. We discuss symmetry about the x-axis, y-axis and the origin and we give methods for determining what, if any symmetry, a graph will have without having to actually graph the function. Examples of Student Work at this Level The student correctly writes and solves the first inequality: We are still going to use the definition of slope, which is: However, if we are not able to factor the polynomial we are unable to do that process.
He cannot be farther away from the person than two feet in either direction. Since the run is positive 3, I counted to the right 3. Quadratic Equations, Part I — In this section we will start looking at solving quadratic equations. Rational Expressions — In this section we will define rational expressions.
Graphing inequalities with two variables can be tricky and is made even more tricky when we graph inequalities with two variables and absolute value. With absolute value graphing, if the inequality is similar to the equation of a line, (for example y > m|x| + b), then we get a V shape, and we shade above or below the V.
Solving Equations and Inequalities - In this chapter we will look at one of the most important topics of the class. The ability to solve equations and inequalities is vital to surviving this class and many of the later math classes you might take. *The Greatest Integer Function, sometimes called the Step Function, returns the greatest integer less than or equal to a number (think of rounding down to an integer).
kcc1 Count to by ones and by tens. kcc2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
kcc3 Write numbers from 0 to Represent a number of objects with a written numeral (with 0 representing a count of no objects). kcc4a When counting objects, say the number names in the standard order, pairing each object with one and only. Writing Exponential and Logarithmic Equations from a Graph Writing Exponential Equations from Points and Graphs.
You may be asked to write exponential equations, such as the following.
