Answer:

I think the answer would be -60 (as in 60 people left each year)

Step-by-step explanation:

If the population decreased by 300 over 5 years, and the same number of residents left each year, then you would divide 300 by 5, and that gives you 60.

Answer:

1. (a) A function is a mapping f:x\rightarrow y 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 x= -5

y=-4(-5)+1=21

When x=-1

y=-4(-1)+1=5

when x=0

y=-4(0)+1=1

when x=2

y=-4(2)+1=-7

when x=10

y=-4(10)+1=39

So, Range is: {-39,-7,1,5,21}

Option 1 is correct.

(c) We have given a function v(c)=98c

Where c is the number of cup jug of milk which is 16.

Put c=16 in given function

v(c)=98\cdot 16

v(c)=1568

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:

f(x)=3x

So, f(x)=y

That is y=3x

We will find x from above equation we get

x=\frac{y}{3}

Now, interchange x and y

y=\frac{x}{3}

\Rightarrow f(x)=\frac{x}{3} is the required inverse

Therefore, option 3rd is correct.
