What are the domain and range of the function on the graph?

Mathematics

Rainbow [258]3 years ago
4 0

we know that

The domain of the function of the graph is the interval-----> (-∞,∞)

that means

All real numbers

The range of the function of the graph is the interval-----> (0,∞)

that means

y> 0 -----> all real numbers greater than zero

therefore

<u>the answer is the option D</u>

The domain includes all real numbers, and the range is y > 0

Answer:

D) The domain includes all real numbers, and the range is y > 0.

Step-by-step explanation:

Given : Graph .

To find : What are the domain and range of the function on the graph.

Solution :

Domain : The domain is the set of all possible x-values .

Range : The range of a function is the complete set of all possible resulting values of the dependent variable y.

We can see from the graph , x values includes all real numbers and range ( y values  greater than 0 because graph line is not intersect at 0 .

Therefore, D) The domain includes all real numbers, and the range is y > 0.

NEED HELP
solmaris [256]

The solutions to the systems of equations are:

1. (2, 3) (see attachment below). [one solution]

2. no solution

3. (3, 13) [one solution]

<h3>Solution to a System of Equations?</h3>

The solution to a system of equations is the x-value and y-value that will make both equations true. It can be found either using a graph, by elimination method, or substitution method as explained below.

1. Using graph to solve y = 2x - 1 and y = 4x - 5:

The solution is the point where both lines intersect which is: (2, 3) (see attachment below). [one solution]

2. Solving using substitution method:

x = -5y + 4 ---> eqn. 1

3x + 15y = -1 ---> eqn. 2

Substitute x = -5y + 4 into eqn. 2

3(-5y + 4) + 15y = -1

-15y + 12 + 15y = -1

-15y + 15y = -1 - 12

0 = -13 (this shows that there is no solution)

3. Using elimination method:

14x = 2y + 16 ---> eqn. 1

5x = y + 2 ---> eqn. 2

1(14x = 2y + 16)

2(5x = y + 2)

14x = 2y + 16 ----> eqn. 3

10x = 2y + 4 -----> eqn. 4

Subtract

4x = 12

x = 12/4

x = 3

Substitute x = 3 into eqn. 2

5(3) = y + 2

15 = y + 2

15 - 2 = y

13 = y

y = 13

The solution is: (3, 13).
