Q. Letg(x)={5−x2e3−x for x≤3 for x>3Is g continuous at x=3 ?Choose 1 answer:(A) Yes(B) No
Check Left-Hand Limit: To determine if g(x) is continuous at x=3, we need to check if the left-hand limit, the right-hand limit, and the value of the function at x=3 are all equal.
Check Right-Hand Limit: First, we find the left-hand limit as x approaches 3 from the left, which means we use the piece of the function defined for x≤3. We substitute x=3 into the first piece of the function:x→3−limg(x)=5−3=2.
Check Function Value at x=3: Next, we find the right-hand limit as x approaches 3 from the right, which means we use the piece of the function defined for x > 3. We substitute x=3 into the second piece of the function:x→3+limg(x)=2e3−3=2e0=2.
Conclusion: Now, we check the value of the function at x=3. Since x=3 falls in the first piece of the function (x≤3), we use the first piece to find g(3):g(3)=5−3=2.
Conclusion: Now, we check the value of the function at x=3. Since x=3 falls in the first piece of the function (x≤3), we use the first piece to find g(3):g(3)=5−3=2.Since the left-hand limit, the right-hand limit, and the value of the function at x=3 are all equal to 2, the function g(x) is continuous at x=3.
