5. Which model is most appropriate for the data shown in the graph below?

Hey there! :)

Exponential.

Step-by-step explanation:

Exponential is the best choice because the graph is increasing geometrically. This means that the parent function of the equation looks like this:

The shape of this equation will resemble an curve that has a horizontal asymptote that the graph will not intersect.

We can also narrow down each choice:

a) Quadratic. Incorrect because the graph pictured is not a parabola.

b) Linear. Incorrect because the rate of change is not constant, and the graph is not a straight line.

c) Most probable answer.

d) Incorrect.

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

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.
