9. what is the equation of the graph?

(3 points) Sinuosoids on the plane have four basic features: amplitude, period, phase shift (sometimes called horizontal shift), and vertical shift (sometimes represented by the equation of the sinusoid's midline). Below is the graph of a particular sinusoid which is the graph of the function f(x). Pi/2 -pi/4 pi/4 1/2 (Click on a graph to enlarge it) Using the graph, determine the amplitude, period, phase shift and midline for the above f(x). . Note, phase shift is sometimes called horizontal shift. Also, the midline should be written as an equation not just a numerical value. Amplitude 1 Period pi/2 Phase shift pi/2 Midline y= 0 Using the trig function sin(x), find an equation for the graph of f (x). . For example, y = 5 sin(6x - 7) + 22.
