Q. Let\newlineh(x)={ex+2 for x2(x+2)e for x>2 h(x)=\left\{\begin{array}{ll} e^{x+2} & \text { for } x \leq-2 \\ (x+2)^{e} & \text { for } x>-2 \end{array}\right. \newlineIs h h continuous at x=2 x=-2 ?\newlineChoose 11 answer:\newline(A) Yes\newline(B) No \mathrm{No}
  1. Check Definition: To determine if h(x)h(x) is continuous at x=2x=-2, we need to check if the following three conditions are met:\newline11. h(x)h(x) is defined at x=2x=-2.\newline22. The limit of h(x)h(x) as xx approaches 2-2 from the left is equal to the limit of h(x)h(x) as xx approaches 2-2 from the right.\newline33. The limit of h(x)h(x) as xx approaches 2-2 is equal to the value of h(x)h(x) at x=2x=-2.
  2. Find Left Limit: First, let's check if h(x)h(x) is defined at x=2x=-2. Since h(x)h(x) has a piece for x2x \leq -2, which is e(x+2)e^{(x+2)}, we can substitute x=2x=-2 into this piece to find h(2)h(-2). \newlineh(2)=e(2+2)=e0=1h(-2) = e^{(-2+2)} = e^0 = 1. \newlineSo, h(x)h(x) is defined at x=2x=-2.
  3. Find Right Limit: Next, we need to find the limit of h(x)h(x) as xx approaches 2-2 from the left. Since the function for x2x \leq -2 is e(x+2)e^{(x+2)}, the limit as xx approaches 2-2 from the left is also e0=1e^0 = 1.
  4. Compare Limits: Now, we need to find the limit of h(x)h(x) as xx approaches 2-2 from the right. The function for x > -2 is (x+2)e(x+2)^e. As xx approaches 2-2 from the right, the expression (x+2)e(x+2)^e approaches 0e0^e. Since any positive number to the power of ee is positive, and 0e0^e is xx11, the limit as xx approaches 2-2 from the right is xx11.
  5. Conclusion: Since the limit of h(x)h(x) as xx approaches 2-2 from the left is 11, and the limit as xx approaches 2-2 from the right is 00, the two limits are not equal. Therefore, h(x)h(x) is not continuous at x=2x=-2 because the limits from the left and right do not match.
