Concept explainers
To graph: The given function. Then identify its domain and range.
Domain:
Range:
Given information:
A function:
Formula used:
The domain of any function is the independent variable values of for which the function is defined.
The range of a function is the dependent variable or y for which a function is defined.
Calculation:
To graph the given function, start with plotting the x -intercepts. It can be seen from the function that x -intercepts are
Plot some points beyond and between the x -intercepts.
x | |||
y |
The given function is a 3rd degree function with positive leading coefficient. Upon graphing all the points and x -intercepts, the required graph would look like as shown below:
The domain of the function is all real values of x or
