Nikolay [14]

Answer:

See attached picture to view the graph

Step-by-step explanation:

Start by analyzing how this average idea works:

If only one member goes to the trip, it will cost him/her $1000+$200 = $1200.

If two members go to the trip, then they will share the cost as per the following: ($1000+ $200 + $200 = $1400) which they will be dividing into two people, thus costing each of them $700.

Notice that the general function that represents such average will be given by: f(x) = \frac{1000+200x}{x}

Plot such function in the two dimensional plane, and you will get the asymptotic behavior shown in the attached image.

W (n) = n^2-n find w (-3)
Papessa [141]

Answer:

w(-3) = 12

Step-by-step explanation:

Plug in -3 for n in the equation:

w(n) = n^2 - n

w(-3) = (-3)^{2} - (-3)

Simplify. Remember to follow PEMDAS. First, solve the power:

w (-3) = (-3)^2 - (-3)\\w (-3) = (-3 * -3) - (-3)\\w (-3) = (9) - (-3)

Next, combine like terms. Note that if there are two negative signs directly next to each other, it becomes a positive sign. Add:

w(-3) = 9 - (-3)\\w(-3) = 9 + 3\\w(-3) = 12

Your answer: w(-3) = 12
