Getting Familiar with Functions

Topic:
Functions
By knowing how the graph of a function looks, it is possible to understand its behaviour. Domain and range of functions can also be read from the graphs. In the following tasks you will plot several functions and answer subsequent questions. if you have the handout then use it to draw the rough sketch and the domain and range. Else make a note of the same in your notebook.

Function1

What is the domain and range of the function ?

Function 2

What is the domain?

Check all that apply

Function 2

What is the range?

Function 3

What is the domain?

Check all that apply

Function 3

What is the range?

Check all that apply

Function 4

What is the domain and range of the function?

Without plotting the function 5, can you predict what the domain and range of f is. Explain how you identified the same.
