1 The Heaviside function is used in engineering applications to model flipping a switch. It is defined below. H(x ) = 1 H x 20 a, Sketch a graph of H on the Interval [-1, 1]. b. Does lim H(x) exist? a. Choose the correct graph below. O A. OB. QC CD. AH AHDI O b. Does lim H(x) exist? O A. Yes, because the function is defined for every value of x in the range [-1. 1]. Textbook
