Answer:
4x^3 + x - 7 if g(X) is 4x^ 3
Step-by-step explanation:
f(X) =x-7
g(X) =4x ^3
f(X) + g(X) = x - 7 + 4x^3
= 4x^3 + x -7
The addition of two given function f(x) = x−7 and g(x) = 4x^3 is f(x) + g(x) = 4x^3 + x -7.
It is the sum of two functions similar to the addition of any two polynomial functions.
So, It given f(x) = x−7 and g(x) = [tex]4x^{3}[/tex]
f(X) + g(X) = x - 7 + [tex]4x^{3}[/tex]
f(X) + g(X) = [tex]4x^{3}[/tex] + x -7
Thus, the addition of two given function f(x) = x−7 and g(x) = [tex]4x^{3}[/tex] is f(X) + g(X) = [tex]4x^{3}[/tex] + x -7.
