Domain And Range Of A Function Example Problems
The range of f x 2 x 1 is 2.
Domain and range of a function example problems. College algebra questions on finding the domain and range of functions with answers are presented. Write an example of a set of ordered pairs that is a function and one that is not a function. The expression defining function f contains a square root.
The range of a function f consists of all values f x it assumes when x ranges over its domain. Find the domain of function f defined by answers to matched problems 1 2 3 and 4. Domain and range of a function explanation examples.
Domain and co domain of f. Thus the domain of the function is left 2 3 right also the variation in the function output is in the continuous interval from 1. We know it is both injective see example 98 and surjective see example 100 therefore it is a bijection.
A function is defined by the equation y 3x 4. Y left t right 3 t 2 2t 1 solution. The expression under the radical has to satisfy the condition 2x 8 0 for the function to take real values.
If the domain is 1 x 5 what is the minimum value in the range of the function. The plot of a function f is shown below. College algebra questions with answers sample 5.
Draw an example of a graph that is a function and one that is not a. Before getting into the topic of domain and range let s briefly describe what a function is. We observe that the graph corresponds to a continuous set of input values from 2 to 3.
