Answer:

Range = (7,5,-1,-9)

Point 1 = ( -3, 7)

Point 2 = ( -2, 5)

Point 3 = ( 1, -1)

Point 4 = ( 5, -9)

Explanation:

g(x)= 1-2x

The domain is x.

The range is y.

g(x) is the function.

To solve this you just input each number from the domain into the function.

g(x) = 1 - 2(-3)

-2 × -3 = positive 6

It is a positive because a negative multipled by a negative equals a positive. This means it is not 1-6 because it is not a negative, it would be 1+6.

1 + 6 = 7

g(x) = 1 -2(-2)

-2 × -2 = positive 4

1 + 4 = 5

g(x)= 1 - 2(1)

-2 × 1 = -2

Since it is multipled 1 time it will be -2. So the equation is still 1-2.

1 - 2 = -1

g(x)= 1 - 2(5)

-2 × 5= -10

A negative multipled by a positive is a negative.

1 - 10 = -9

Now that you have all the numbers put them in parentheses things like the domain

Range = {7,5,-1,-9}

To graph it you need to put in each point by finding the first number of the domain and range and that is your point.

The first point would be (-3,7) and so on and so forth.
