3. I NEED HELP ASAP!! Find the range of f(x)=-x+4 for the domain (-3, -2, -1, 1).

A. (-7, -6, -5, 3)

B. (7, 6, 5, 4)

C. (7, 6, 5, 3)

D. (-7, -6, -5, -4)

C (7,6,5,3)

Step-by-step explanation:

Domain of a function are the x values and Range are the y values.

since f(x) = y, simply plug in the values provided in the question to the function for x.

Example:

f(x) = -x + 4

f(-3) = -(-3) + 4

Plug in the values and simplify.

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.
