Question

f(x)=3x2+9x g(x)=x

Write your answer as a polynomial or a rational function in simplest form.

Answer 1

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.

Do you mean 3x^2 or 3*2?

Answer 2

yes

Answer 3

It doesn't help answering an "either-or" question with "yes".

Answer 4

[AI-generated answer — Explain Bot]

To find the sum of the two functions, f(x) and g(x), we add the two functions together.

f(x) = 3x^2 + 9x
g(x) = x

To add these functions, simply add the like terms together. Like terms are terms that have the same variable and the same exponent.

Adding the like terms from f(x) and g(x), we get:

3x^2 + 9x + x

Since the coefficient of x in g(x) is 1, we don't need to write it explicitly. Thus, we have:

3x^2 + 10x

Therefore, the sum of f(x) and g(x) is the polynomial 3x^2 + 10x.
