Required
Determine the average rate of change;
From the given parameters, it can be seen that the number of vehicles is a function of year
Let x represent the years and y represent the number of vehicles;
Such that;
The rate of change is calculate as follows;
Hence, the average rate of change is 1970.5 thousand

Step-by-step explanation:
The formula for finding the area of a circle is;
Where () represents the area of the circle, (
) represents the value (
) and (
) represents the radius of the circle. As per its definition, the diameter is the largest cord or line segment that can be drawn through a circle, the diameter always passes through the center of a circle. The radius ( a line segment that can be drawn from the center of the circle to any side of the circle) is always half of the diameter.
This means that the radius for the given circle is (), since (
÷
)
Substitute these values into the equation and solve for the area of the circle.

Answer:
1. (a) A function is a mapping where there should be different values of y for different x.
So, given ordered pairs:
(3,7), (3,8) ,(3,-2) ,(3,4) ,(3,1)
It is not a function because there are multiple y values for single x-value.
Option 2 is correct.
(b) We need to find range of the function f(x)= -4x +1
So, we have given the domain which means the value of x we will put thses given values of x to find y
Values of y is the range in a function
So, given domain is: {-5,-1,0,2,10}
When
When
when
when
when
So, Range is: {-39,-7,1,5,21}
Option 1 is correct.
(c) We have given a function
Where c is the number of cup jug of milk which is 16.
Put c=16 in given function
So, c=16, v(c)=1568 is reasonable domain and range of the function.
Option 1 is correct.
(d) We need to find the inverse of given ordered pairs (1,2) (3,4) ,(6,8)
So, the inverse means values of x and y interchange.
So, the required inverse is: (2,1) ,(4,3) ,(8,6)
Option 3rd is correct.
2. We need to find the inverse of given scatter plot in which we have to find the inverse
So, given scatter plot represents (-4,-2) ,(1,-1) ,(2,1) ,(3,2)
So, in inverse values of x and y interchange
So, inverse scatter plot should represent (-2,-4) ,(-1,1) ,(1,2), (2,3)
Attached is the scatter plot inverse
Graph 1 is correct.
3.We have been given a function:
So, f(x)=y
That is
We will find x from above equation we get
Now, interchange x and y
is the required inverse
Therefore, option 3rd is correct.
