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} Functio

poizon [28]

Answer:

$D = \{-2,-1,3,5\}$ -- Domain

$R = \{-7,0,4\}$ -- Range

It is a function

Step-by-step explanation:

Given

$D = \{-2,-1,3,5\}$

$R = \{-7,0,4\}$

Required

State the domain and range

Determine if the relation is a function

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

$D = \{-2,-1,3,5\}$ -- Domain

$R = \{-7,0,4\}$ -- 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

<em>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.</em>

what is an equation of the line that s perpendicullar to y-3=-4(x+2) and passes through the point (-5,7)

Sidana [21]

Answer:

4y=x+33

y=x/4+33/4 (slope-intercept form)

Step-by-step explanation:

y-3 = -4(x+2)

y-3 -4x-8

y= -4x-8+3

y= -4x-5

m1 = -4

For perpendicularity

m2= -1/-4 = 1/4

The equation is

y-y1 = m2(x-x1)

y-7 = 1/4(x-(-5))

y-7 = x/4+5/4

Multiply through by 4

4y-28=x+5

4y=x+5+28

4y=x+33

Divide through by 4

y=x/4+33/4 (slope-intercept form)
