MEDALS!!
The cost to produce a product is modeled by the function f(x) = 5x2 - 70x + 258 where x is the number of products produced. Complete the square to determine the minimum cost of producing this product.

Answer 1

5(x - 7)2 + 13; The minimum cost to produce the product is $13.
5(x - 7)2 + 13; The minimum cost to produce the product is $7.
5(x - 7)2 + 258; The minimum cost to produce the product is $7.
5(x - 7)2 + 258; The minimum cost to produce the product is $258.
