Let f and g be functions given by f(x)=x^3 and g(x)=x^2 lxl

a)find f(1/2), g(3), and g(negative square root of 2)

b) what is the domain of f?

c) what is the range of g?

d) evaluate f(-3)+g(-3)

e) compare and contrast f and g

f) is there a value of x such that f(x)-g(x)=128? if so find x. if not explain why no such value exists

g) is there a value of x such that f(x)-g(x)=-54? if so find x if not explain why no such value exists
