Step-by-step explanation:

Answer 2

The statement which is true about this radical function is; Choice A; As x approaches positive infinity, f(x) approaches positive infinity.

Which statement is true about the radical function?

From the task content; it follows that the given radical function is; f(x) = -√x+6.

On this note, when the value of x is positive infinity, the root of x approaches positive infinity. However, the negative coefficient of the radical renders the value of f(x) negative infinity as 6 is infinitesimal in comparison.
