The graph of a function g is shown.The x y-coordinate plane is given. A function labeled y = g(x) with 4 parts is graphed.The first part is a curve, enters the window in the second quadrant, goes up and right becoming less steep, crosses the y-axis at approximately y = 2.5, and ends at the open point (2, 3).The second part is a curve begins again at the open point (2, 1), goes up and right becoming less steep, and ends at the open point (5, 2).The third part is the closed approximate point (5, 1.2).The fourth part is a curve, begins at the open point (5, 2) goes down and right becoming more steep, and exits the window in the first quadrant.Use it to state the values (if they exist) of the following:(a)  lim x → 2− g(x)(b)  lim x → 2+ g(x)(c)  lim x → 2 g(x)(d)  lim x → 5− g(x)(e)  lim x → 5+ g(x)(f)  lim x → 5 g(x)SolutionLooking at the graph we see that the values of g(x) approach as x approaches 2 from the left, but they approach as x approaches 2 from the right.Therefore (a) lim x → 2− g(x) =     and    (b) lim x → 2+ g(x) = .Since the left and right limits are different, we conclude that (c) the limit as x approaches 2 of g(x) does not exist.The graph also shows that (d) lim x → 5− g(x) =     and    (e) lim x → 5+ g(x) = .This time, the left and right limits are the same and so, by this theorem, we have (f) lim x → 5 g(x) = Despite this fact, notice that g(5) ≠ 2.

The graph of a function g is shown. The x y-coordinate plane is given. The curve begins at the point (−2, 0), goes up and right, passes through the point (−1.5, 1), goes up and right, changes direction at the point (−1, 1.5), goes down and right, passes through the point (−0.5, 1), goes down and right, passes through the origin, goes down and right, passes through the point (0.5, −1), goes down and right, changes direction at the point (1, −1.5), goes up and right, passes through the point (1.5, −0.5), goes up and right, changes direction at the point (2, 0.5), goes down and right, crosses the x-axis at x = 2.5, goes down and right, changes direction at the point (3, −1), goes up and right, passes through the point (3.5, −0.5), goes up and right, and ends at the point (4, 0.5).

For the function h whose graph is given, state the value of each quantity, if it exists. (If an answer does not exist, enter DNE.)The x y coordinate plane is given. The curve enters the window at the point (−5, 0), goes up and right to the open point (−3, 4), and goes down and right to the closed point (0, 1). The curve starts again at the open point (0, −1), goes up and right to the open point (2, 2), and then oscillates at an increasing rate between y = 2 and y = 4 until it reaches the x-value of 5. Between the x-values of 4.5 and 5 the oscillations are too close together to distinguish individual curves. At (5, 3) the oscillations stop and the curve goes up and right, changes direction at the approximate point (7, 4.8), goes down and right, and exits the window in the second quadrant.(a)lim x → −3− h(x)(b)lim x → −3+ h(x)(c)lim x → −3 h(x)(d)h(−3)(e)lim x → 0− h(x)(f)lim x → 0+ h(x)(g)lim x → 0 h(x)(h)h(0)(i)lim x → 2 h(x)(j)h(2)(k)lim x → 5+ h(x)(l)lim x → 5− h(x)
