Homework Statement
Find the range of h
Homework Equations
h(x) = sqrt(25 + (x - 3)2)
The Attempt at a Solution
I factored out the (x-3)2 and simplified to get
sqrt(x2 - 6x + 34)
I was trying to figure out the domain first, knowing that x2 - 6x >= -34 in order for the number inside the sqrt to be non-negative.. I don't know, maybe I'm missing something really basic here. Help? :)
