Which of these equations has a graph that is tangent to the x-axis at one of its intercepts? choose all the polynomials that have this property.
y = x^2 + 6x + 9
y = –x^3
y = (x + 2)(x + 6)^2
y = (x – 5)(x + 3)(x + 1)(x – 5)
y = x^4

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)) =
