Use the graphs to determine the value of each expression below. Graph A Graph B f(1) =] f(1) = lim f(z) = lim f(I) = lim f(z) = lim f(z) = lim f(z) = lim f(I) = Graph C Graph D f(1) = f(1) = lim f(x) = I-,1 lim f(z) = lim f(z) - lim f(z) = lim f(z) - lim f(z) = . all answers should be given as numbers if a result does not exist, respond with "DNE" or "undefined"
