Math Problem Statement
Find the point(s) on the graph of f where the tangent line is horizontal. (If an answer does not exist, enter DNE.) f(x) = x/x2+16 (x, y) = ( ) (smaller x-value) (x, y) = ( ) (larger x-value)

Formulas
Quotient Rule: (u/v)' = (u'v - uv') / v^2
Derivative of f(x) = x/(x^2 + 16): f'(x) = (-x^2 + 16) / (x^2 + 16)^2
Theorems
Conditions for Horizontal Tangents: Derivative equals zero
