Please help this is timed For which function and interval can the extreme value theorem be applied?
f(x) =х/(x-6)^2 over the interval [3, 5] f(x) = -5/2(x-7)^3 over the interval (6, 8)
f(x) = 4 tan(πX) over the interval [0, 1]
f(x) = 3e^x + 1 over the interval (1, 3)

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)) =
