Find the function h(x)= f(x)+g(x) if f(x)=2x^3+1 and g(x)=x^2-4x+3

h(x)= f(x)+g(x) = 2x^3 + x^2 - 4x + 4

Step-by-step explanation:

You find the function transformation by adding the two equations together. Since f(x)=2x^3+1 and g(x)=x^2-4x+3, then h(x)= f(x)+g(x) = 2x^3+1 + x^2-4x+3 = 2x^3 + x^2 - 4x + 4.
