Describe a relationship that can be modeled by the function shown in the table, and explain how the function models the relationship. x f(x)1 44 89 1216 1625 20

y = 4·√x

Step-by-step explanation:

f(x) is defined as a product of 4 into √x

4 × √1 = 4

4 × √4 = 8

4 × √9 = 12

4 × √16 = 16

4 × √25= 20

Hence, the relationship is defined as : y is 4 times the square root of x

i.e. y = f(x) = 4·√x

f(x) is 4 times the square root of x

Step-by-step explanation:

4 × √1 = 4  

i.e. f(1)=4·√1

4 × √4 = 8  

i.e. f(4)=4·√4

4 × √9 = 12  

i.e. f(9)=4·√9

4 × √16 = 16  

i.e. f(16)=4·√16

4 × √25= 20  

i.e. f(25)=4·√25

As we can clearly see, f(x) is 4 times the square root of x

i.e.  f(x) = 4·√x

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
