Question

If f(x)=2x and g(x)=−2x3+2x, then what is f(x)+g(x)?

x3+2x



−4x3+2x



−2x3+4x



2x

Answer 1

`-2x^3+4x`

Explanation:

I am assuming that the functions are:

`f(x)=2x\\\\g(x)=-2x^3+2x`

-----------------------

`f(x)+g(x)\\\\2x+-2x^3+2x\\\\2x+2x+-2x^3\\\\4x+-2x^3\\\\\boxed{-2x^3+4x}`

Hope this helps you!
