The function f(x)=-x^2-2x+15 is shown on the graph. what are the domain and range of the function?

Domain is all real numbers

y ≤ 16

Step-by-step explanation:

The domain is the set of x values that the graph covers. There is no restriction on the x values. The domain is all real numbers.

The range is the set of y values that the graph covers. The highest the y values go is 16 at the top of the parabola. So the range is y ≤ 16.

domain is set of all real numbers

Range is

Step-by-step explanation:

Domain is the set of x values for which the function is defined

In f(x), we have y values for all x values, So there is no restriction for x

Hence domain is set of all real numbers

Range is the set of all y values for which the function is defined

From the graph of the given function f(x), the maximum point that is vertex at (-1,16)

The range of the function is y<=16

Range is

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

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.
