(will give BRAINLIEST)The formula for the perimeter of a rectangle Is P = 2(1+w). Part A. Rewrite the formula for the perimeter
shepuryov [24]
A. W = P/2 - 1

B. First you need to divide both sides by 2 to get rid of the 2 on the side of the w. Then you need to take 1 away from both sides.

Whatever you do to one side, you must do to the other.

Which statement is true about the end behavior of the function represented by the graph?
Zepler [3.9K]

End behavior always involves x approaching positive and negative infinity. So we'll cross off the choice that says "x approaches 1".

The graphs shows both endpoints going down forever. So both endpoints are going to negative infinity regardless if x goes to either infinity.

<h3>Answer: Choice B</h3><h3>As x approaches −∞, f(x) approaches −∞, and as x approaches ∞, f(x) approaches −∞.</h3>

Another way to phrase this would be to say "f(x) approaches negative infinity when x goes to either positive or negative infinity"
