Find the the relation and use it to write an equation for the statement. Then sote the equation, y varies inversely as the square of x 1 and y= 4/63 when x = 3 find y when x = 5

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

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)) =
