For each function below, find its domain and then determine if the function increasing, decreasing, or constant on each piece of the domain. Sometimes the domain is just one interval but functions still changes its behavior at some points. f(r)=5r^2-4
The domain is
The interval on which the function is increasing ( )( )
The interval on which the function is decreasing( ) ( )
The interval on which the function is constant ( ) ( )
