Can you please answer this?

all real numbers i think

Step-by-step explanation:

its all real numbers. SKATE OR DIE

Step-by-step explanation:

The correct option is A) all real numbers.

Step-by-step explanation:

Consider the provided function.

Domain of the function is the set of input values which a function can take or the domain is the set of all possible x values which a function can take.

Now consider the provided function.

The above function can take any value of x and defined for all real numbers.

The graph of the above function is shown in figure 1.

Now if we observe the graph of the function we can concluded that the function is defined for any value of x.

Also the function is continues everywhere on the real number line.

Hence, the domain of the provided functions is all real numbers.

Thus, the correct option is A) all real numbers.

step-by-step explanation:

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.
