So the 4 represents the amplitude of the function. We can also see that because it is a positive number, the graph is even. ⁽⁽The number before the graph type (Sin or Cos) always represents the amplitude. The amplitude is how many units the graph travels up and down from the midline. 
The -2 is the midline. This means that the midline is at -2 on the Y-axis. To find the max and min, you then add the amplitude to find the maximum, and subtract to find the minimum. [-6. 2]
To find the period, you divide 2π by the term in front of x. In this case, it's 3, so we do 2π/3. This cannot be simplified further, but in degrees this equals 120°. This means that, with the question asking for 2 full cycles, that the graph will go through 2 full cycles in 240°

Hope this helps, sorry i couldn't sketch the graph for you

Choose the correct symbol to complete the statement.4.105 _____ 4.15

<
>
=

Answers

The correct inequality symbol would be <, 4.105<4.15. This is because 4.15 is larger than 4.105. When the right side number is greater than the left side, the inequality symbol would be <. But if its the other way, that the laft side is greater than the right side, the symbol would be >.

Answer:

<

Step-by-step explanation:

4.15 is a larger number than 4.105. So it would look like 4.105<4.15

Answer:

The first and 3rd are functions, but the second and fourth are not functions.

Step-by-step explanation:

To see if something is a function, use the vertical line test. If there are multiple y coordinates for a singular point for x, it is not a function.

A two pound box of spaghetti costs $2.50. Philip says that the unit cost is 2/2.50 =$0.80 per pound. Explain his error

Answers

Answer

Find out the  Philip error.

To prove

As given

A two pound box of spaghetti costs $2.50.

Philip\ says\ that\ the\ unit\ cost\ is\ (2)/(2.50) is\ equal\ 0.80\ dollar\ per\ pound.

Philip calculated the unit cost by wrong method he divided weight by the cost which is wrong.

2 pound box of spaghetti costs = $2.50

one\ costs\ of\ box = (Total\ cost\ of\ two\ pound\ cost)/(Total\ pounds)

unit\ cost\ of\ box = (2.50)/(2)

unit cost of box = $1.25

Therefore the unit cost of box is $1.25 .
2.50 / 2 = 1.25 not .80It also looks like you are trying to divide the spaghetti boxes by the price, when it should be price by number of boxes.
