Me in the robison’s neighborhood celebrate the holidays by putting up decorations. the function f(x)=4√x represents the number of households f(x) in the neighborhood that have decorations on the xth day of december until the 25th. complete the table of values.

Step-by-step explanation:

If f(x) = 4√x,

then f(0) = 4√0 which is 4 × 0 = 0

and f(1) = 4√1 which is 4 × 1 = 4 and

f(4) = 4√4 which is 4 × 2 = 8 and

f(9) = 4√9 which is 4 × 3 = 12 and

f(16) = 4√16 which is 4 × 4 = 16 and

f(25) = 4√25 which is 4 × 5 = 20

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
