(TIMED TEST) Use the graph of the function to estimate intervals on which the function is increasing, decreasing, or constant. Support the answer numerically. From the graph, it appears that: A function f(x) = -1/2 x^2 + x + 4 is decreasing for _. A function f(x) = -1/2 x^2 + x + 4 is increasing for _. The critical points is _.

Multiplying an even number of negative numbers gives an answer that is choose from:

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)) =
