$\"\"$

The general form of the graph of sine function is $\"\"$ .

The function is $\"\"$ .

The amplitude of g(x) is $\"\"$ and its period is $\"\"$ .

To find the left and right endpoints of a one - cycle interval then $\"\"$ .

To solve the equation 1: $\"\"$ .

To solve the equation 2: $\"\"$ . $\"\"$

The function $\"\"$ is obtained by a horizontal shrink of two, and one cycle of g(x) corresponds to the interval $\"\"$ .
