    Help with Question Clarification

    I am working on my module for Uni Calculus and this is what the question is asking (my answers are in red):

    f(x) = 2x^2 - 4x -5

    (a) if it has a max value or min value: Min
    (b) The value is ____. It occurs at x = 1

    When it says "the value is" what is it asking for?

    You're asked to give the minimal value of the function, i.e. f(x_0) where x_0 is the minimum point. In your case, they're asking for the value of f(1)
