    Need help with Input and Output

    Please help me with C) and D).

    For C) I have no idea how to solve it because there is no z on the graph.

    And for D), is the answer "since f(b) = -f(d), we know the graph is symmetrical"

    C) Notice Q has the coordinates (d,e) e = f(d) x = d


    D) since c= f(0) it follows z = 0 f(x) =0 for x = h

    E) if f(b) = -f(d) What do you mean by symmetrical? symmetrical with respect to what? Any way knowing the relationship beteween just 2 points can't allow you to make any statements about f(x) in general.

    Note the graph is not symmetrical wrt x axis or y axis.

    What you can conclude is a = - e since f(b) = a and f(d) = e

    Thank you so much for helping me with these problems. I meant to say D) and E) because I already understand C) but it was good that you went over all of them anyways. Thanks for going the extra mile for helping me understand this!
