Which of the following rational functions is graphed below?
Zepler [3.9K]

Answer:

  D.  F(x) = 1/(x +5)²

Step-by-step explanation:

The vertical asymptote at x=-5 tells you that x=-5 will be a zero of the denominator. The only equation with a denominator factor of (x+5) is ...

  F(x) = 1/(x +5)²

_____

<em>Additional comment</em>

The fact that the value of F(x) does not change sign at the vertical asymptote tells you the denominator factor will be of even degree. That is taken for granted here, as all denominators are squares in the answer choices.

Select the correct answer from each drop-down menu.
sdas [7]

Answer:

see below

Step-by-step explanation:

12 banana muffins, 10 chocolate muffins, 6 blueberry muffins, and 7 vanilla muffins.

The total number of muffins is 35 muffins

P(vanilla) = number of vanilla/ total

               = 7/35

               = 1/5

This is not likely to occur so it is an unlikely event

Solution to 7(y-3) =2(y-9) +2y
dolphi86 [110]
<h3><u>The value of y is equal to 1.</u></h3>

7(y - 3) = 2(y - 9) + 2y

Distributive property.

7y - 21 = 2y - 18 + 2y

Combine like terms.

7y - 21 = 4y - 18

Subtract 4y from both sides.

3y - 21 = -18

Add 21 to both sides.

3y = 3

Divide both sides by 3.

y = 1
