Determine if the statement is true or false. If it is false, explain why.
5.
All linear functions are increasing.
6.
Arithmetic sequences are an example of linear functions.
7.
Exponential functions have a domain that includes all real numbers.
8.
Geometric sequences have a domain that includes all integers.
9.
The range for an exponential function includes all real numbers.
10.
All linear relationships are functions with a domain and range containing all real numbers.
For each of the following functions, find the desired features.
