    No that's not correct what is the value of f(x) when x = 0?

    read it off the graph

    then plug in x = 0 and f(x) = above values and see which one fits

    X=1 gives f(x) =0 so which option satisfies this?? :)

    In such questions your strategy should be to find a point (x, y) which lies on the graph and then put these values of x nd y in the options given. The one which satisfies is the answer if more than one options satisfy then u musttake another point nd check
