Given:
The graph of a function is given.
To find:
The range of the graph.
Solution:
We know that, the domain is the set of input values and range is the set of output values.
In a graph, domain is represented by the x-axis and range is represented by the y-axis.
From the given graph it is clear that there is an open circle at (-8,-8) and a closed circle at (3,4). It means the function is not defined at (-8,-8) but defined for (3,4).
The graph of the function is defined over the interval . So, the domain is (-8,3].
The values of the function lie in the interval . So, the range is (-8,4].
Therefore, the range of the function are all real values over the interval (-8,4].
Answer:
Step-by-step explanation:
By definition the domain of an inverse function is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function , then to find the inverse function, follow these steps:
1. Make
2. Solve for the variable "x":
3. Exchange the variable "x" with the variable "y":
4. Exchange "y" with. Then the inverse function is:
