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
1. For what values of x is R=0

Best ResponseYou've already chosen the best response.0So you are trying to find when R = 0, which is when f(x) = 0, which is when 3x^21/3x^3 = 0 Start by factoring, what factors are common in both terms on the left of the equation?

Best ResponseYou've already chosen the best response.0ok, not 3, but yes x, and another x can be factored out too: x^2(3  1/3x) = 0 Then each part can equal zero to make the whole thing equal zero because they are being multiplied

Best ResponseYou've already chosen the best response.0...so solve x^2 = 0 and 31/3x = 0 and you have both solutions...

Best ResponseYou've already chosen the best response.0to solve 3  1/3x = 0: 3  1/3x = 0 add 1/3x to each side 3  1/3x + 1/3x = 0 + 1/3x on the left they cancel by subtraction and on the right, the zero is extra: 3 + 0 = 1/3x...

Best ResponseYou've already chosen the best response.0...then the zero on the right is extra: 3 = 1/3x Then, since x is being multiplied by 1/3, you do the operation that would "undo" that, which is multiply by 3 (same as divide by 1/3) again on both sides: 3*3 = 3*1/3x 9 = 1x 9 = x Second solution
