A doctor who is treated a heart patient wants to presicribe medication to lowere the patients blood pressure. The body's reaction to this medication is a function of the dose admininistered. If the patient takes x milliters of the medication, his blood pressure should decrease by r=f(x) points where
f(x)=3x^21/3x^3
what values of x make sence for this function

Best ResponseYou've already chosen the best response.0Okay, Im not sure I understand the question, sorry o.O Because at x=0 f(x) =0 as well. I believe. I don't think that helps in anyway. Sorry

Best ResponseYou've already chosen the best response.0Any value greater than 0 would make sense. right..

Best ResponseYou've already chosen the best response.0no its what values of x make sence for this function

Best ResponseYou've already chosen the best response.0i think we want the maximum for f(x) so that his blood pressure reduces the most right?

Best ResponseYou've already chosen the best response.0well, any values of x will work except for x=0

Best ResponseYou've already chosen the best response.0y = 3x^21  is this the function we are working with? 3x^3

Best ResponseYou've already chosen the best response.0then lets see where this function is increaseing and decreasing for x

Best ResponseYou've already chosen the best response.0Domain should be any value greater than 0. But I don't think its that simple.

Best ResponseYou've already chosen the best response.0nned function to be decreasing, or blood pressure is not decreasing

Best ResponseYou've already chosen the best response.0the 1st derivative is: 3x^3(2x)  9x^2(3x^21) 21x^4 +9x^2  9x^6

Best ResponseYou've already chosen the best response.0when the derivative is zero we get the highes and lowes of it;

Best ResponseYou've already chosen the best response.03x^2 (7x^2 3) = 0 when x = 0 and... sqrt(12)/14 = sqrt(3)/7 the only value here that makes sense is sqrt(3/7)

Best ResponseYou've already chosen the best response.0now is it a high or a low :) or an inflection point is there an answer key for this to determine if we are doing it right :)

Best ResponseYou've already chosen the best response.03x^21  3x^3 3 sqrt.3/7^21  3 sqrt.3/7^3 40/49  thats a negative number so id say its not going to be that point :) 9/49 (sqrt.3/7)

Best ResponseYou've already chosen the best response.0lets see what the roots are if any to this equation when 3x^21 =0 3x^2 = 1 x^2 = 1/3 x = sqrt(1/3) = sqrt(3)/3 is a zero
