For (f:\mathbb{R}\to\mathbb{R}), (f(x)=x^5+x), what is the correct analysis for onto property?

Answer and explanation

Correct answer: It is onto because continuity and end behavior ensure some (x) for every real (y)

Step 1: (x^5+x) is a continuous odd-degree polynomial. Step 2: It tends to (\infty) as (x\to\infty) and to (-\infty) as (x\to-\infty). Step 3: At expert level, combine continuity with end behavior to conclude.
