Question

F(x)=x+1 g(x)=x³
so what is f(x)+g(x)

Answer 1

Answer:
`x^(3)+x+1`

Explanation:

When you're asked to add functions together you add as if they were polynomials

Answer 2

f(x) + g(x) = x³ + x + 1

Explanation:

In order to find f(x) + g(x), we need to add the two functions f(x) and g(x) together:

f(x) = x + 1

g(x) = x³

f(x) + g(x) = (x + 1) + (x³)

Now, we can combine the terms:

f(x) + g(x) = x + 1 + x³

So, the sum of f(x) and g(x) is:

f(x) + g(x) = x³ + x + 1
