Struggling, can anyone help me out on these three functions? It would be much appreciated. Thanks so much!! :)
Maurinko [17]

Answer:

1. a) Not function

b) Domain is all real numbers greater than or equal 2 (x ≥ 2)

c) The range all real numbers ( -∞ < y < ∞)

2. a) Function

b) The domain is all real numbers (-∞ < x < ∞)

c) The range is all real number greater than or equal -4 (y ≥ -4)

3. a) Not function

b) domain is {-3 , -2 , -1 , 0 , 1 , 3}

c) The range is {-2 , -1 , 1 , 2 , 3 , 5}

Step-by-step explanation:

1. Not a function because some x has more than one corresponding y

Note: If we draw vertical line and move it left and right over the curve it will cut the cure in more than one point that means one x has more than one y

2. Function because every x has one corresponding y

3. Not function because some x have more than one corresponding y like

   (-3 , -2) (-3 , 2) and (3 , -1) (3 , 2)

What is the common difference, d, of the sequence? −92, −74, −56, −38, −20, ... Enter your answer in the box.
Bingel [31]
Hello! The common distance of the sequence is 18. This is because 74 and 92 are 18 units apart, 74 and 56 are 18 units apart, 56 and 38 are 18 units apart, and so on. You can find the difference of the sequence by finding the distance between two numbers.

John is digging a hole for a swimming pool,the hole will be 28 feet long, 5 feet wide, 34 feet wide. How much cubic feet of dirt
ivann1987 [24]

Answer:

John need to remove <u>4760 cubic feet</u> of dirt.

Step-by-step explanation:

Given:

John is digging a hole for a swimming pool,the hole will be 28 feet long, 5 feet wide, 34 feet wide.

Now, to find the cubic feet of dirt John need to remove.

Length = 28 feet.

Width = 5 feet.

Height = 34 feet.

<u><em>As the swimming pool is in the shape of a rectangular prism.</em></u>

So, we put formula of volume to get the cubic feet of dirt need to remove:

Volume = length\times width\times height

Volume=28\times 5\times 34

Volume=4760\ cubic\ feet.

Therefore, John need to remove 4760 cubic feet of dirt.
