    You are given the zeros k and l, of the quadratic so you should know that the quadratic is this a(x-k)(x-l). What are k and l? (We will use the max here in a sec)

    Wait. This doesn't make sense. How can the max value be at x=25 when 25 is not beteeen -3 and 2. Do they mean the max value is 25?

    Well if you decide to come back...Since they are talking about min/max, you can refer also to the vertex form of a parabola: a(x-h)+m where (h,m) is vertex. Have a good day.
