If f(x)=x^2x and g(x)=1/x, and h(x) is defined with the expressions below, arrange the values of h'(1) from smallest to largest.
1. h(x) = f(x)g(x)
2. h(x) = f(x)g(x)
3. h(x) = f(x)/g(x)

Best ResponseYou've already chosen the best response.1for 2 h'(1) =f'(1)g(1)+g'(1)f(1) 3 h'(1) =( f'(1) g(1)  f(1)g'(1) )/ (g(1))^2 this the answer @IrishBoy123 right lol
