Please help I will give Brainliest answer

B f(n) = 2 * 3^(n-1)

Step-by-step explanation:

A. f(n) = (n-1)^2 +3

          3, 4,7,12,19

B f(n) = 2 * 3^(n-1)

          2,6,8,54, 162

This is the solution

C f(n) = 2^n +1

3,5,9,17,33

D f(n) = 3n

  3,6,9,12,15

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
