The point of diminishing returns (x , y ) is  (11, 21462)

Step-by-step explanation:

From the question we are told that

     The function is  

Here R(x)  represents revenue (in thousands of dollars) and  x  represents the amount spent on advertising (in thousands of dollars).

           Now  differentiating  R(x) we have  

Finding the second derivative of R(x)

at  inflection point    

    So      

=>          

    substituting value of x into R(x)

Now the point of diminishing returns (x , y ) i.e (x , R(x) ) is

     (11, 21462)

step-by-step explanation:

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
