Find the аmplitude, periоd, frequency, аnd verticаl shift оf the functiоn whose graph is given below if the point((a, f(a))= (6pi, -frac{7}{3})) and ((b, f(b) ) = (8pi, 1)). (If the answer is a fraction, write it using the "/" symbol. For example, if the answer is (frac{2 pi}{3}), write "2pi/3".) Amplitude = [amplitude] Period = [period] Vertical Shift = [vert]
