Q.1 Question 1 Let f(x)=\left(\frac{\ln (x)}{x}\right)^{2} Q 1.1 Question 1 Part (a) \text { Find } f^{\prime}(x) \text { . Show all work. } Q1.2 Question 1 Part (b) Find

all critical points of f(x) on the interval (0, oo). Q 1.3 Question 1 Part (c) Find the global minimum and maximum of f(x) on the interval (0, ) and clearly state the x-values where they occur. Explain your reasoning. If a global minimum/maximum does not exist,simply state so and, again, explain your reasoning as to why.
