❶Did you know… We have over college courses that prepare you to earn credit by exam that is accepted by over 1, colleges and universities. Equations of higher order may have more solutions, or none.

## Topics from your homework you'll be able to complete:

Provide those who help with as much information as possible. Demonstrate that you have already put in some thought and effort into solving the problem.

If you post an essay for editing or other help, create a Google doc or similar. Walls-of-text are almost impossible to edit with any effectiveness. Be sure your doc is accessible to those who will read your essay. Remove all personal information prior to posting. This subreddit is for help, pushes in the right direction, not answers. Think of this as an anonymous tutoring center.

With that in mind, the moderators have sole discretion to remove any post they feel violates that idea. Advertisements of any form.

This includes asking for "likes," page views, or similar things. Posts tagged "urgent," "ASAP," "important," "due in an hour," etc. Requests for help with cheating, plagiarism, or other violations of academic integrity; violations of copyright or terms of use; or other illegal or unethical activities.

Keep in mind that we do not and will not have any sort of vetting procedure for responders. Accept answers at your own risk. We use automoderator for a few things. It may delete a post erroneously. We ban all bots. Would it be possible to have more than one solution? Question word for word from my textbook: Use finite differences to determine an equation for the function.

There are lots in fact infinitely many functions that could go through those given points. Before this question can be answered, you need to disclose what type of function you are looking for. Are you looking for a polynomial of a certain degree? You mention " the polynomial function", as though there is only one. I could come up with a 10th degree or a 4th degree polynomial that goes through all of those points. Notice they said "an" equation.

Each point will correspond to an equation. For example, the point -3, 40 would produce the equation. Repeat this process for the other four points. Then you will have a matrix of coefficients which will be augmented with the y-values.

It will have 5 rows and 6 columns. Learn how easy it is to use on any linear system in two variables. After watching this video lesson, you will be able to solve a linear system in three variables using the elimination method. Learn the simple operations that are needed to solve your system. In this video lesson, you will learn to recognize when a linear system has no solution or an infinite number of solutions. You will also learn how to go about solving each of these types of systems. In this lesson, we will learn about the identity matrix, which is a square matrix that has some unique properties.

We will discover that a given matrix may have more than one identity matrix. Most word problems require that you find the value of one variable.

But, what if there is more than one unknown variable? Systems of equations are extremely useful in applications where there is more than one unknown. We will explore applications that involve systems of equations and look at how to set up a system of equations with given information. In this lesson, we will quickly review what a 2x2 system of equations is, and then we will look at how to apply these systems to real world problems.

We will see how to set up a system to correspond to a problem and discuss solutions. Solving systems of equations that have three equations and three variables can be a challenge.

In this lesson, you will learn how to identify additive inverses that will help you to solve the system using the elimination method. Systems of linear equations with no solution or infinitely many solutions are special systems of linear equations. This lesson will explore what happens when we try to solve these special systems of linear equations both graphically and algebraically.
