Graph the given relation or equation and find the domain and range. then determine whether the relation or equation is a function. (3.3, 5.3), (–1.7, 5.3), (–4.7, 3.3), (–4.7, –2.7)

Domain:

Range:

The relation is not a function.

Explanation:

The coordinates are plotted in the graph. The image of the graph is attached below.

The domain of a relation is the set of all x-values for which the function is well defined. Thus, the domain are

The range of a relation is the set of all y-values obtained by substituting the values for x in the function. Thus, the range are

The relation is not a function since, -4.7 has two different y-values. By definition of function, the function cannot have two different y-values for the same x-value.

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

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.
