Good evening ,
Answer:
{(1,6),(2,2),(4,7),(3,2)}
Step-by-step explanation:
As a function , f has a unique image for each number of the domain.
for instance, the first set can’t represent a function because 1 has more than one image(number).

Answer:
The table represents a linear function because the rate of change is constant or all the points lie on a straight line.
Step-by-step explanation:
From the given table it is noticed that the line passing through the points (2,5), (4,10), (6,15) and (8,20).
The slope of the line is
m= y2-y1/x2-x1 = 10-5/4-2 = 5/2
The slope of line is . It means the value of y increased by 5 if the value of x increased by 2.
From the given points we can noticed that the value of y increased by 5 if the value of x increased by 2. So, the function has same slope for any two points.
Since the rate of change (slope) is same for all points, therefore the table represents a linear function.
If we plot these points on a coordinate plane and connect then we get a straight line. I means it is a linear function.
Answer: -1
Step-by-step explanation:
8-13=s+4s
-5=5s
-5/5=5s/5
-1=s
You need to translate the angles using this function (x,y) to (x+3,y-3)
first of all find A and B and C
A=(0,3),B=(-1,1),C=(2,1)
After the translation
A'=(3,0),B'=(2,-2),C'=(5,-2)
