e) OO, STC 5 TT 6 ' 12 f) None of the above. Review Later Question 6 Write a sine function with a positive vertical displacement given the following information: the amplitude is 3, the horizontal shift is 9/2 to the left, y-intercept is (0, -4), and the period is 6. a) Of (x) = 3sin(zx+57 + 1 b) of (x) = 3 sin(2x - 57 ) +1 c) of ( x) = 3 sin( zx - 3x ) - 1 d) of (x) = 3 sin (~x + 5")- 1 e) of (x) = 3sin (x+ 2 f) ONone of the above. Review Later Question 7 The current / , in amperes, flowing through an AC (alternating current) circuit at time t is I(t) = 210 sin (30 at - 2 ) , where t 2 0. Find the period and the horizontal shift. MacBook Pro esc Search o enter
