WebBut if the formal definition of whether a function is continuous is lim_x->c f(c) = f(c), and you have a graph with a jump discontinuity at both ends of a point... Example f(x)={x if 0 < x < 2, 5 - x if 2 < x < 4} Since both the limit and f(x) are undefined at x = 2, would the formal definition be proving the graph continuous?? WebSolution : lim x-> x0- f(x) = f(x 0) (Because we have unfilled circle). But, lim x-> x0+ f(x) ≠ f(x 0) (Because we have filled circle at different place). Hence the given function is not continuous at the point x = x 0.. Question 2 : …
