Question

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

Answer 1

I post an image instead.
Correction: g(3)=(3²)|3|=9(3)=27
