If (f:\mathbb{R}\to \mathbb{R}) is defined by (f(x)=5), what is the correct conclusion?

Answer and explanation

Correct answer: Not onto

Step 1: The constant function (f(x)=5) always gives only (5). Step 2: Other codomain values such as (4) and (6) are not obtained. Step 3: If the range has only one value and the codomain is larger, the function is not onto.
