You can put this solution on YOUR website! Determine the domain and range of the function.
f(x)= sqrt(x+16) , x < 4
::::::::::(x-5)^2 , x >= 4
===================================
Domain:
solve x+16 must be >= 0
x >= -16
---
Therefore, Domain is All Real Numbers >=-16
===============================================
Range:
sqrt and (x-5)^2 are both >= 0
Range is All Real Numbers >= 0
===============================================
