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.
1 Which transformation best describes the
relationship between the functions
?
1)
2)
3)
4)
reflection in the line
reflection in the origin
reflection in the x-axis
reflection in the y-axis
2 If
, which function represents the
reflection of
in the y-axis?
1)
2)
3)
4)
and
3 The graph of the function
is shown on
the accompanying set of axes. On the same set
of axes, sketch the reflection of
in the yaxis. State the coordinates of the point where
the graphs intersect.
