The critical points of a rational inequality are –1, 3, and 4. Which set of points can be tested to find a complete solution to the inequality? x = 1 and x = 3.5
x = –1, x = 3, and x = 4
x = –2, x = 2, and x = 5
x = –3, x = 1, x = 3.5, and x = 5

Translate the word phrase into a math expression. 15 fewer than the product of 4 and a number. (pls immediately)

Someone answer asap 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)) =
