Best ResponseYou've already chosen the best response.0Trying to solve this directly you get lim(x > 5)(f(x)) = 0/0 therefore, you can apply L'Hopital's rule. Taking the derivative of the top and the bottom, you get lim(x > 5)(f(x)) = lim(x > 5)(1/(1/(2*sqrt(x1)))) = lim(x > 5)(2*sqrt(x1)). Putting x into this equation, you get lim(x > 5)(f(x)) = 4

Best ResponseYou've already chosen the best response.0How does the bottom equal 1/(2xsqrt(x1))? If the bottom is (sqrt(x1) 2, how does a 2 get in front of the sqrt? I got 1/2(x1)^(1/2)

Best ResponseYou've already chosen the best response.0Exactly, that is in the denominator 1/(1/2*(x1)^(1/2)) so move it all to the top canceling the 1's and you get 2*sqrt(x1)
