READ THIS AND THEN ANSWER THE QUESTION
There are so many items for sale in our world! Some of the items you can buy will appreciate in value. This means that as time passes, the value of the item increases. If you decide to sell the item at a later time, you should be able to sell it for more than you paid. Some common examples of items that appreciate in value include houses, stocks, and some types of art.
Other items you can buy will depreciate in value. This means that as time passes, the value of the item decreases. If you decide to sell the item at a later time, you will likely have to sell it for less than you paid for it. Cars, game systems, and jewelry are examples of items that usually depreciate as time passes. The majority of items that depreciate never reach a value of $0. Their worth attains some minimum, positive value that is greater than $0 and then their price stabilizes.
In 1981, IBM manufactured and sold one of the first personal computers. The machine was called the IBM Personal Computer (PC) 5150 and the full model retailed for $3,000. Similar to modern technology, the value of this item depreciated over time. The function that models how the PC 5150 depreciated as time passed is , where x is the number of years after 1981 and f(x) is the value of the PC 5150.
Use what you have learned about quadratic functions to help you answer these questions.
1. Evaluate the depreciation function at f(0). Show your work and use function notation as needed. What does this number represent?
2. Find the vertex of the depreciation function. What does this point represent in context of this problem? Show your work and explain your process.

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
