Answer: D

<u>Step-by-step explanation:</u>

f(x) = 2x g(x) = x² - 1

f(g(x)) = 2(x² - 1)

= 2x² - 2

g(f(x)) = (2x)² - 1

= 4x² - 1

Bonnie volunteers to bring bags of candy to her child's class for the Halloween party this year. She buys one bag of candy A

jeka57 [31]

Answer: Bonnie can make 40 treat bags. Each treat bag has three pieces of Candy A, 11 pieces of Candy B, and 13 pieces of Candy C.

Step-by-step explanation:

Since there's no number of student's in her child's class, I did this:

I found the common factors of 120, 440, and 520. And found out that the GCF (greatest common factor) is 40.

120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120.

440: 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440.

520: 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520.

After finding out that the GCF is 40, I took the numbers 120, 440, and 520, and divided them by 40.

120 divided by 40 = 3

440 divided by 40 = 11

520 divided by 40 = 13

Therefore Bonnie can make 40 treats bags with no candy pieces left behind.

HELP PLEASE!!! <br>the question and answer are in the image attached

RideAnS [48]

Answer:

$g(x)=\sqrt[3]{x-3}+4$

Step-by-step explanation:

The function g(x) is a shifted version of the function f(x); f(x) is shifted by 3 along x-axis and by 4 along y-axis.

Another way of thinking about this is that the function g(x) contains points (3, 4); therefore,

$g(x)=\sqrt[3]{x-3}+4$

which goes through the point (3, 4).
