The value, in dollars, of an antique has increased exponentially over x years as shown in the graph. image What are the domain and range of the function? A. Domain: x ≥ 0 Range: y ≥ 0 B. Domain: x ≥ 0 Range: y ≥ 1,000 C. Domain: all real numbers Range: y ≥ 1,000 D. Domain: all real numbers Range: y ≥ 0

C. Domain: all real numbers Range: y ≥ 1,000

Step-by-step explanation:

0 to 10 years = 50

30 to 40 years = 150

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.

yes
