An electrical circuit switches instantaneously from a 2 volt battery to a 12 volt battery 5 seconds after being turned on Sketch on a sheet of paper a graph the battery voltage against time. Then fill in the formulas below for the function represented by your graph. Fort -.: II, V[t) :II Fort '2 IiI, V[t) =IiI. At what point or points is your function discontinuous? t :l:_| (Give your answer as a commaiseparated fist, or enter the word none if there are no discontinuities.)
