BigorU [14]

Answer:

The correct option is:

100 + 0.8(x - 100) = 250

Step-by-step explanation:

We are given that:

We know that a department store gives 20 % off the portion of the bill that is over 100 dollars.

Total bill is 250 and x is the amount of money she would have spent without the promotion.

The cost to which the discount applies is 0.8 ( x - 100 ).

<em>Finally the equation we get is 100 + 0.8 (x - 100) = 250.</em>

Help me find the range of this function please
lara31 [8.8K]

Answer:

{-2, -14, -26, -50}

Step-by-step explanation:

The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:

- For x = -8

f(x)=-2x-18

f(-8)=-2(-8)-18

f(-8)=16-18

f(-8)=-2

The first value of the range of the function is -2

- For x = -2

f(x)=-2x-18

f(-2)=-2(-2)-18

f(-2)=4-18

f(-2)=-14

The second value of the range is -14

- For x = 4

f(x)=-2x-18

f(4)=-2(4)-18

f(4)=-8-18

f(4)=-26

Th third values of the range is -26

- For x = 16

f(x)=-2x-18

f(16)=-2(16)-18

f(16)=-32-18

f(16)=-50

The fourth and last value of the range is -50

Now we can put all the values of the range together

The range of the function is {-2, -14, -26, -50}
