FAN AND MEDAL!!
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.

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.
