Choose the equation that does not represent the function of the graph shown below.
y = 3 sin 8x
y = -3 sin 8(x + pi)
y = 3 sin 8(x - pi/2)
y = -3 sin 8x
The equation for that graph is f(x) = 3 sin 8x. Nothing else is correct. THere is no horizontal shift (phase shift), nor is there vertical shift. Just a period adjustment.
