The functions mapping R into R are defined as:
f(x) = x^{3}-4^{x}, g(x)=1/(x^{2}+1) and h(x)=x^{4}
Then find the value of the following composite functions: hog(x) and hogof(x)
- (x^{2}+1)^{4} and [(x^{3}-4x)^{2}+1]^{4}
- (x^{2}+1)^{4} and [(x^{3}-4x)^{2}+1]^{-4}
- (x^{2}+1)^{-4} and [(x^{3}-4x)^{2}+1]^{4}
- (x^{2}+1)^{-4} and [(x^{3}-4x)^{2}+1]^{-4}
