Find the domain and range of each relation. Then determine if the relation is a function. D={-2, -1, 3, 5}, R={-7 ,0 ,4} Function?

Answers

Answer 1

Answer:

[tex]D = \{-2,-1,3,5\}[/tex] -- Domain

[tex]R = \{-7,0,4\}[/tex] -- Range

It is a function

Step-by-step explanation:

Given

[tex]D = \{-2,-1,3,5\}[/tex]

[tex]R = \{-7,0,4\}[/tex]

Required

State the domain and range

Determine if the relation is a function

From the question, we have the domain and range as:

[tex]D = \{-2,-1,3,5\}[/tex] -- Domain

[tex]R = \{-7,0,4\}[/tex] -- Range

Next, is to determine if the relation is a function or not.

Yes, it is a function.

The number of elements in the domain is 4

The number of elements in the range is 3

When the domain has more elements than the range, this is called a many-to-one function, and it is a valid type of function.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.


Given inequality, the relation is 5x-9>12. The solution to inequality be done as:-

5x - 9 > 12

5x > 12 + 9

5x > 21

x > 21 / 5

Therefore, the given relation 5x-9>12 represents inequality. the solution of inequality is x > ( 21 / 5).

I need help asap !!
​

Answers

Answer:

Slope is 0

Equation is y = -2

Step-by-step explanation:

To get the slope, we need the coordinates of its end points

These are;

((-2,-2) and (2,-2)

The formula for the slope is;

m = (y2-y1)/(x2-x1)

m = (-2+2)/(2 + 2) = 0/4 = 0

Since the slope is 0, the only thing left in the equation is the y-intercept

This is according to the question-2

So the equation of the line is

y = -2
