An electrical circuit switches instantaneously from a 10 volt battery to a 82 volt battery 40 seconds after being turned on. Sketch on a sheet of paper a graph the battery voltage, V, against time, t. Then ll in the formulas below for the function represented by your graph. Mg 132% At what point or points is your function discontinuous? Answer: t : seconds. (ifthere is more than one point of discontinuity, separate them with commas)
