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"

Can someone help me understand this ? The app doesn’t understand the equation
butalik [34]

Answer:

c; 1 / (a^12)(b^8)

Step-by-step explanation:

when the exponent is outside a number you multiply the outside exponent by the inside exponent

so far after multiplying exponents you have

a^-12 / b^8

but you must put the 12 on the bottom so that all exponents can be positive

1 / (a^12)(b^8)

Three-fourths was subtracted from a number, and then 5/4 was added to the result. The sum was -7.
Rasek [7]

Hi there!

Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :

(x - \frac{3}{4}) + \frac{5}{4} = -7

subtract \frac{5}{4} on each side of the equation


x - \frac{3}{4} = -8.25

add \frac{3}{4} on each side of the equation

x = -7.5


-7.5 - 3/4 = -8.25

-8.25 + 5/4 = <u>-7</u>


So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.


There you go! I really hope this helped, if there's anything just let me know! :)

Andy randomly selects an outfit to go to school. He can choose from 4 shirts: blue stripes, red stripes, black or white stripes.
denpristay [2]

Answer:

B and D

Step-by-step explanation:

The probability that Andy chooses a striped shirt and a pair of blue shorts is:

\frac{3}{4} * \frac{1}{3} = \frac{3}{12} = \frac{1}{4}

The probability that Andy chooses a striped shirt and pair of tan or plaid shorts is:

\frac{3}{4} * (\frac{1}{3} + \frac{1}{3}) = \frac{6}{12} = \frac{1}{2}

Please help me out and answer!!!!! <br> Really struggling
e-lub [12.9K]

Answer:

D

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y) → (- y, x)

A translation of 3 units up → + 3 in the y- direction, that is add 3 to the y- coordinate, hence

(x, y) → (- y, x) → (- y, x+ 3) → D
