Create Team. Q&A for work. A dedicated place to share your team’s knowledge. How to write chained inequalities (a <= b <= c) in if functions. Ask Question -1. How can you write the following in if functions in R. Supposing you have X ranging from 121 to 212 and Y ranges from 122 to 212, how can you write an if function to represents something like: if 121 <= X <= 212 and 122 <= Y <= 212... The two inequalities, x ? 0 and y ? 0, are what keep the graph of the system in the first quadrant. The values of x and y are never negative in a system with this requirement; they have to be positive or zero.

Inequalities have two forms, one that includes the condition of being equal, and one that does not. The inequality x<5 excludes 5, while in x?5 includes 5. To graph x<5, draw an open circle at 5. This divides the number line into two regions, one below 5 and one above 5. Test the region that includes 0. Is 0 less than 5? Yes. So shade or draw a thick line from the circle at 5 to the left

In this lesson you will learn to create an inequality given a word problem by using algebraic reasoning.

**Linear Functions and Linear Inequalities in Two Variables**

A linear inequality describes an area of the coordinate plane that has a boundary line. Every point in that region is a solution of the inequality. Every point in that region is a solution of the inequality.... Functions are mathematical entities that assign unique outputs to given inputs. Sounds simple? Think again! In this topic you will evaluate, graph, analyze, and create various types of functions.

## How To Create Inequalities Given A Function

### Let us know how to make an inequality: Algebraic operations with inequalities are possible but first we will have to identity the type of operation to be performed like addition, subtraction, multiplication or cross multiplication, division etc.

- variable arc x whose trig functions make the inequality R(x) true. Transform the given trig inequality into standard form R(x) > 0 (or < 0). Example. The inequality (cos 2x < 2 + 3sin x) will be transformed into standard form: R(x) = cos 2x – 3sin x - 2 < 0 Page 3 of 8. Example. The inequality (sin x + sin 2x > - sin 3x) will be transformed into standard form R(x) = sin x + sin 2x + sin
- Suppose that we are given the graph of the equation. There is an easy way to see if this equation describes y as a function of x. There is an easy way to see if this equation describes y as a function …
- Function[Function, Number a, Number b]: Yields a function graph, that is equal to f on the interval [a, b] and not defined outside of [a, b]. Note: This command should be used only in order to display functions in a certain interval.
- You may be asked to write a piecewise function, given a graph. Now that we know what piecewise functions are all about, it’s not that bad! To review how to obtain equations from linear graphs, see Obtaining the Equations of a Line, and from quadratics, see Finding a Quadratic Equation from Points or a Graph. Here are the graphs, with explanations on how to derive their piecewise equations
