b)(-5,-6)
c)(-5,-24)
d)(-7,-6)

    In general, you can translate the graph of a function to the right (+x direction) by h if you transform the function from f(x) to f(x-h).

    A reflection about the x-axis is done by transforming from f(x) to -f(x).

    A stretching by a factor of k in the y-direction requires a transformation of f(x) to k.f(x). For example, a stretching of twice in the y-direction would require a transformaton from f(x) to 2f(x).

    The given transformation is a combination of all of the three transformations above.
