One step at a time
Function range definition
The set of values of the dependent variable for which a function is defined
Find the minimum and maximum value in each defined interval and unite the results
Domain of √x2+1:−∞<x<∞
Extreme Points of √x2+1:Minimum(0,1)
Find the range for the interval −∞<x<∞:1≤f(x)<∞
Combine the ranges of all domain intervals to obtain the function range
