What is the range of the function f(x) = (x + 3)2 + 4?

Range of is [4,∞).

Step-by-step explanation:

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,∞).

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
