Question

Which function has a domain of x 25 and a range of y s3?

Answer 1

Step-by-step explanation:

The function has a domain x ≥ 5.

This is because the function remains real for (x - 5) ≥ 0 as negative within the square root is imaginary.

Hence, (x - 5) ≥ 0

⇒ x ≥ 5

Now, for all x values that are greater than equal to 5 the value of will be negative.

So,

⇒

⇒ y ≤ 3

Therefore, the range of the function is y ≤ 3. (Answer)
