Which equation best represents this data set? {(-4,-4.8), (-3, -8.2), (-2,-9.1), (-1, -8.1), (0, -4.7), (1,0.3)}
y= 1.1x – 4.2
y= 1.1x² + 4.2x – 4.9
y= 1.1x² + 4.2x + 4.9
y = 1.1x + 4.2

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)) =
