What is the domain and range of each relation?
LUCKY_DIMON [66]

Answer:

\text{Domain of}R_1=\{-2,0,2,4\}  and \text{Range of}R_1=\{-3,-1,0\}

\text{Domain of}R_2=\{-3,-1,0,3\}  and \text{Range of}R_2=\{-1,0,1,2,3\}

Step-by-step explanation:

Domain is the set of input values or x-values.

Range is the set of output values or y-values.

According to the relation mapping diagram, the relation is

R_1=\{(-2,-3),(-2,-1),(0,0),(2,0),(4,-3)\}

So,

\text{Domain of}R_1=\{-2,0,2,4\}

\text{Range of}R_1=\{-3,-1,0\}

In the graph 5 points are plotted. So, the relation is  

R_2=\{(-3,1),(-1,-1),(0,0),(3,2),(3,3)\}

So,

\text{Domain of}R_2=\{-3,-1,0,3\}

\text{Range of}R_2=\{-1,0,1,2,3\}

Write (2 4) and (6 16) in the form y=mx+b
Lena [83]

Answer:

y = 3x-2

Step-by-step explanation:

We can find the slope using the formula

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

  = (16-4)/(6-2)

  =12/4

 =3

We then use the point slope form of a line

y-y1= m(x-x1)

y-4 = 3(x-2)

Distribute the 3

y-4= 3x-6

Add 4 to each side

y-4+4 = 3x-6+4

y = 3x-2

This is in slope intercept form
