Abby collected data modeling a company's costs versus its profits. The data are shown in the table:
x g(x)
−3 12
−1 −4
0 0
2 32

Which of the following is a true statement for this function?

The function is decreasing from x = −3 to x = −1.
The function is increasing from x = −3 to x = −1.
The function is decreasing from x = −1 to x = 0.
The function is decreasing from x = 0 to x = 2.

The function is decreasing from x = −3 to x = −1 is the answer

Step-by-step explanation:

I took the test and got this question correct.

The function is decreasing from x = −3 to x = −1 is the answer

Step-by-step explanation:

I took the test

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
