Provide an appropriate response.As x moves from left to right though the point c = 3, is the graph of f(x) = x + 
rising, or is it falling? Give reasons for your answer.
What will be an ideal response?
The derivative of the function is f'(x) = 1 - 
, which is positive for all x > 1. By the first derivative test, the function is increasing at c = 3.
