Domain Reciprocal Function Interval Notation
Its domain is x x 0 its range is also x x 0 as an exponent.
Domain reciprocal function interval notation. It is an odd function. It is a hyperbola. Keep in mind that in determining domains and ranges we need to consider what is physically possible or meaningful in. This is its graph.
In interval notation the domain is 1973 2008 and the range is about 180 2010. In functions and function notation we were introduced to the concepts of domain and range. Write domain and range given an equation. The function f x x2 has a domain of all real numbers x can be anything and a range that is greater than or equal to zero.
The table below gives a summary of interval notation. In this section we will practice determining domains and ranges for specific functions. Its domain is the real numbers except 0 because 1 0 is undefined. If f x 1 x 2.
Domain 1950 2002 range 47 000 000 89 000 000. We can also use inequalities or other statements that might define sets of values or data to describe the domain in set builder notation. The domain is the set of real numbers. Since an interval might or might not contain its endpoints we use square brackets when endpoints are included in the interval and parentheses when endpoints are not included.
Given figure identify the domain and range using interval notation. In interval form the domain of f is. For the domain and the range we approximate the smallest and largest values since they do not fall exactly on the grid lines. F x 5 x x3.
Open parentheses closed parentheses infinity imagine an 8 sideways negative infinity an 8 sideways with a negative sign in front of it and union a symbol similar to an elongated u. Interval notation is a method used to write the domain and range of a function. Interval notation and set notation. Denominators can t be 0 so the domain is x 2 or inf 2 u 2 inf in interval notation the only way a fraction can be 0 is if the numerator is 0.
This is the reciprocal function. The reciprocal function can also be written as an exponent. Two ways in which the domain and range of a function can be written are. In the previous examples we used interval notation to describe the domain of functions.
For example x 10 x 30 describes the allowed values of x in set builder notation.
