Domain And Range Of Y X 2
Here are some examples illustrating how to ask for the domain and range.
Domain and range of y x 2. In this case there is no real number that makes the expression undefined. Find the domain of 1 e 1 x 1 function domain. The range on the other hand is different. As a function table and as a set of coordinates.
For math science nutrition history. Find the domain and range y x 2 y x2 y x 2 the domain of the expression is all real numbers except where the expression is undefined. The example below shows two different ways that a function can be represented. From the above graph you can see that the range for x 2 green and 4x 2 25 red graph is positive.
Square root of cos x. Find the domain and range y 2. Domain of log x x 2 1 x 2 1 domain. You can take a good guess at this point that it is the set of all positive real numbers based on looking at the graph.
The domain of the expression is all real numbers except where the expression is undefined. In this case there is no real number that makes the expression undefined. Compute answers using wolfram s breakthrough technology knowledgebase relied on by millions of students professionals. We know that any number raised to the second power will always yield a positive.
The domain and range of a function is all the possible values of the independent variable x for which y is defined. Find the domain and range of a function with a table of values. Y x x 2 x 1 yx 2 y 1 x y 0. For the range of y we have.
Make a table of values on your graphing calculator see. How to make a table of values on the ti89. Thus the domain is all real numbers or from infinity to infinity. The range of a function is all the possible values of the dependent variable y.
Hence the function is defined for all x as the denominator is never zero therefore domain of y is the complete set of real numbers i e. Is a straight line perpendicular to the y axis at point which means that the range is a set of one value.
