Consider the table below x y 0 3 1 6 2 r what value of r will make the table a representation of an exponential function? explain your answer

The answer is 12 

SOLVINGS

An exponential function is represented as y = f(x) = a · b^x

As given in the table,

When x = 0, y = 3

y = a · b^x

3 = a(b^0)

3 = a

a = 3

y = a · b^x

a = 3

Therefore, y = 3 · b^x

As given in the table,

When x = 1, y = 6

y = 3 · b^x

6 = 3 · b^1

6 = 3b

3b = 6

b =2

y = 3 · b^x

b = 3

y = 3 · 2^x

As given in the table,

When x =2, y = r

y = 3 · 2^x

r = 3 · 2^2

r = 3 · 4

r = 12 

12 is value of r that will make the table a representation of an exponential function.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
