9-69.

Graph at least two cycles of the following functions.

1. $f(x) = 3$ sin $2(x -\frac { \pi } { 4 }) + 1$

1. $g(x) =\frac { 1 } { 2 }$ cos $\frac { 1 } { 4 }(x + π)$

Identify the amplitude, period, horizontal shift, and vertical shift for each function.

Review the Math Notes box in Lesson 7.2.4 for help identifying the important parts of the function.
