Step-by-step explanation:
2/3 = 0.6 repeating
3/7 = 0.42857
(2200 rev/min) x (360 deg/rev) x ( min/60 sec) = 13,200 degrees per second
(2200 rev/min) x (2 pi radians/rev) x (min / 60 sec) = <u>73 and 1/3 pi</u> radians/sec
let's recall the vertical line test, it's a function if when dropping a vertical line on the graph, it only touches it once on the way down.
