Mighty Cable Company manufactures cable that sells for $120 per meter. For a cable of fixed length, the. cost of producing a portion of the cable varies with its distance from the beginning of the cable. FREE-RESPONSE SOLUTIONS ~ 2015 AB 7 Question AB-5 (a) f has a relative maximum at x = –2, because f ′(x) changes sign from positive to negative there. (b) For the graph of f to be concave down, f ′ must be decreasing. For f to be decreasing, f ′ must be negative. These two conditions together are met on the intervals −<<−21x and 13<x < .
