CC.F.BF.3: Identify the effect on the graph of replacing f(x) by f(x)+k, kf(x), f(kx),
and f(x+k) for specific values of k (both positive and negative); find the value of k
given the graphs. Experiment with cases and illustrate an explanation of the effects
on the graph using technology. Include recognizing even and odd functions from
their graphs and algebraic expressions for them.

4 Two parabolic arches are to be built. The equation of the first arch can be expressed as
, with a range of
, and the second arch is created by the transformation
. On the accompanying set of axes, graph the equations of the two arches. Graph the
line of symmetry formed by the parabola and its transformation and label it with the
proper equation.
