Answer:
-- Domain
-- Range
It is a function
Step-by-step explanation:
Given
![D = \{-2,-1,3,5\}](https://tex.z-dn.net/?f=D%20%3D%20%5C%7B-2%2C-1%2C3%2C5%5C%7D)
![R = \{-7,0,4\}](https://tex.z-dn.net/?f=R%20%3D%20%5C%7B-7%2C0%2C4%5C%7D)
Required
State the domain and range
Determine if the relation is a function
From the question, we have the domain and range as:
-- Domain
-- 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>
Answer:
A
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
n(A)+n(B) [n(A)=cardinal numbers of set A.so we have to count the elements and write .
=4+5
=9
Answer:
Step-by-step explanation:
slope=m=(Y2-Y1)/(X2-X1)
As given values
take, (X1,Y1)=(-7,-4)
(X2-Y2)=(8,8)
hence X1=-7 , Y1= -4 , X2=8 , Y2= 8
putt the values in the above equation of slope we get ,
m=(8-(-4))/(8-(-7)
m=12/15 Ans
Answer:
![\frac{2}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B15%7D)
Step-by-step explanation:
÷ 6 × 1 = ![\frac{2}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B15%7D)
=> He gave them ![\frac{2}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B15%7D)
