Let f ( x ) = x 2 and g ( x ) = x + 6 , find: a . ( f ∘ g ) ( x ) = b . ( g ∘ f ) ( x ) = c . ( f ∘ g ) ( − 3 ) = d . ( g ∘ f ) ( − 3).

Solve the system of equations. y= 2x y= x^2 - 15

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)) =
