An electrical circuit switches instantaneously from a 39 volt battery to a 77 volt battery 9 seconds after being turned on. Sketch on a sheet of paper a graph the battery voltage, V, against time, t. Then fill in the formulas below for the function represented by your graph. V(t) = ift < ift > At what point or points is your function discontinuous? Answer: t= sec seconds. (if there is more than one point of discontinuity, separate them with commas) Select a blank to input an answer
