Range of is [4,∞).
<u>Step-by-step explanation:</u>
Here we have , function , We need to find range of this function . Let's find out:
In the function , Let's focus on : It's a perfect square whose value will be always positive and greater then equal to zero i.e.
⇒ , So minimum value of is 0 at x=-3 . ∴
⇒
⇒
⇒
Minimum value of is 4 , And maximum value of can be ∞ as value of x can be increased . Therefore , Range of is [4,∞).
