Provide an appropriate response.For the function given, show how you would find the average rate of change using the difference quotient. f(x) = 16 + 2x
What will be an ideal response?
The difference quotient is given by 
. So, using 16 + 2x for f(x), we have 
, which simplifies to 
, which simplifies to 2.
