Let R(x)=3x3+2x2+x and S(x)=4x2+1. Find R(x)+S(x).


Sagot :

The function  R(x) + S(x) exists given by [tex]3x^3+6x^2+x+1[/tex].

What is a function?

An expression, rule, or law that describes a relationship between one variable (independent variable) and another variable (dependent variable) exists named a function.

Let the functions be [tex]R(x)=3x^3+2x^2+x[/tex] and [tex]S(x)=4x^2+1.[/tex]

Adding both of the equations, we get

[tex]$R(x)+S(x)=(3x^3+2x^2+x) +(4x^2+1)[/tex]

simplifying both of the equations we get

[tex]$R(x)+S(x)=3x^3+2x^2+x+4x^2+1[/tex]

[tex]=3x^3+6x^2+x+1[/tex]

Therefore, the function  R(x) + S(x) exists given by [tex]3x^3+6x^2+x+1[/tex].
