**How to Determine a Function’s Range**

- Take the function y = f(x).
- The range of the function is the spread of all y values from least to maximum.
- Replace all the values of x in the supplied expression of y to see if it is positive, negative, or equal to certain other values.
- Determine y’s minimum and maximum values.
- Then create a graph for it.

“It is feasible to constrain the range by specifying the codomain of that function,” says one intriguing aspect concerning range and codomain. The set of all positive integers or negative real numbers, for example, must be the codomain of f(x). In this scenario, the function’s result must be a positive integer, and the domain will be restricted appropriately.

For example, if we input -2, we get y = (-2)*3 = -8, which means that when we input -2, the result is -8, which is inside our range. We have our range when we find each of the related outputs to our inputs. As these are the outputs correlating to -2, -1, 0, 1, and 2 respectively, the range in our example is -8, -1, 0, 1, 8.

**Significance of range of functions in the IIT JEE exam**

The IIT JEE is an entrance examination for admission to the undergraduate engineering programmes offered by the Indian Institutes of Technology. The examination is conducted in two stages: the JEE Main and the JEE Advanced. The JEE Main is an all-India examination, while the JEE Advanced is conducted by the IITs for their own admissions.

The range of functions in the IIT JEE exam is vast and varied. The examination tests the students’ understanding of a range of topics, from basic mathematics and physics to more complex concepts in engineering. The examination is designed to test the students’ ability to think critically and apply their knowledge to solve problems.

The range of functions in the IIT JEE exam is important because it helps to assess the students’ understanding of a wide range of topics. The examination tests the students’ ability to think critically and apply their knowledge to solve problems. This is important for undergraduate engineering programmes, where the students need to have a strong foundation in mathematics and physics, as well as engineering concepts.

The range of functions in the IIT JEE exam is also important because it helps to identify the best students for admission to the IITs. The IITs are some of the best engineering colleges in the world, and the students who are admitted to these colleges are some of the brightest and most talented students in the country. The range of functions in the IIT JEE exam helps to identify these students and give them the opportunity to study at the IITs.

**FAQs**

**Q. What Does the Term “Range” Mean in Statistics?**

**Ans: **In statistics, a range is simply a request that you discover the greatest and lowest values in your data collection and then calculate the difference between them.

**Q. What’s the Difference Between Range and Domain?**

**Ans: **First, each value in the domain set correlates to only one value in a function’s range. It is conceivable, however, for more than one domain value to correspond to the same value in that function’s range.

**Q. How Can I Define the Difference Between Range and Domain?**

**Ans: **The domain is represented by a class’s students, while the function or “math machine” is represented by the class itself. The range is determined by your annual grades.
