Select the functions that have identical graphs.

Mathematics
1 answer:
Elan Coil [88]4 years ago
3 0

Answer:

c. 1 and 3

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot each equation.

Please see the attached image below, to find more information about the graph

s

The equations are:

1) y = sin (3x + π/6)

2) y = cos (3x - π/6)

3) y = cos (3x - π/3)

Looking at the graphs, we can see that the identical ones

are equations one and three

Correct option:

c. 1 and 3

Identify the form of the equation –3x – y = –2. To graph the equation, would you use the given form or change to another form? E
Leviafan [203]
You would want to change it to slope intercept form which is y = -3x + 2
putting it in the form you can quickly see that 2 is the y-intercept, which is where it crosses the y axis when the x value is 0.  You can also see than your slope is negative so your line will be going down.  Also, you can tell the slope of the line (rise over run)

popcorn kernels are sold in one-pound bags.If four ounces of kernels make two quarts if popped popcorn,how many bags of kernels
Anon25 [30]
Popcorn kernels in 1 lb bags.
4 ounces of kernels make two quartz of popped popcorn

Number of bag of kernels to fill ten gallons of popped popcorn.

1 pound = 16 ounces
16 ounces / 4 ounces = 4 
4 * 2 quarts = 8 quarts
8 quarts / 4 quarts per gallon = 2 gallons

1 pound bag of popcorn kernel produces 2 gallons worth of popped popcorn.

To make 10 gallons worth of popped popcorn, you need 5 1-pound bags of popcorn kernels.

Two numbers have a difference of 12. The smaller of the two numbers is 3 less than double the other. What are the two numbers?
nexus9112 [7]

Answer:

-9,-21

Step-by-step explanation:

let the numbers be x and y and x>y

x-y=12

y=2x-3

x-(2x-3)=12

x-2x+3=12

-x=12-3

-x=9

x=-9

y=2(-9)-3=-18-3=-21

Each graph shows a relation. The first and second numbers of each ordered pair in the relation are members of the set of real nu
Goshia [24]

Using it's concepts, we have that:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.
  • Since each value of the input is mapped to only one value of y, it is a function.

<h3>What are the domain and the range of a relation?</h3>

  • The domain of a relation is the set that contains all possible input values for the relation. In a graph, it is given by the values of x.
  • The range of a relation is the set that contains all possible output values for the relation. In a graph, it is given by the values of y.

Hence:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.

<h3>When does a relation represents a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

From this graph, we have that <u>each value of x is mapped to only one value of y</u>, that is, there are no vertically aligned points, hence the relation is a function.
