Answer:

  • 3^x
  • 9, 15, 33, 87, 249
  • (4, 87) for example

Step-by-step explanation:

a) First differences of the f(x) values in the table are ...

  19 -13 = 6, 37 -19 = 18, 91 -37 = 54, 253 -91 = 162

The second differences are not constant:

  18 -6 = 12, 54 -18 = 36, 162 -54 = 108

But, we notice that both the first and second differences have a common ratio. This is characteristic of an exponential function. The common ratio is 18/6 = 3, so the parent function is 3^x.

__

b) Translating a function down 4 units subtracts 4 from each y-value. The values of f(x) in the table would be ...

  9, 15, 33, 87, 249

__

c) The x-values of the function stay the same for a vertical translation, so the points in the table of the transformed function are ...

  (x, f(x)) = (1, 9), (2, 15), (3, 33), (4, 87), (5, 249)

A parent volunteer group is raising money by making custom hats to sell at school activities. They plan to sell the hats for $12
Misha Larkins [42]

Answer:

B. (12-6) n - 50

Step-by-step explanation:

Given that:

Cost of making hat = $6 per hat

Selling price = $12 per hat

Advert cost = $50

Number of hats made = n

The profit or money raised from the sales of hat:

Total Revenue from sales - total cost of production - advert cost

Total Revenue from sales = ($12 * n) = $12n

Total cost of production = ($6 * n) = $6n

Advert cost = $50

Hence,

12n - (6n + 50)

12n - 6n - 50

(12 - 6)n - 50
