Over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function
The tide measures 4.35 ft at midnight rises to a high of 8.3 ft, falls to a low of 0.4 ft, and then rises
to 4.35 ft by the next midnight.
What is the equation for the sine function f(2), where x represents time in hours since the
beginning of the 24-hour period, that models the situation?

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
