Limits: graphical approach

	Left- and right-handed limits of a function may be different or the same © Dorothy Wallace
	limit as x approaches 1 from the right of G(x) = 0 © Dorothy Wallace
	limit as x approaches 3 from the left of G(x) = 0 © Dorothy Wallace
	limit as x approaches 3 of G(x) = 0; limit as x approaches 1 of G(x) is undefined © Dorothy Wallace
