Q. Leth(x)={e2xe5x for x<0 for x≥0Is h continuous at x=0 ?Choose 1 answer:(A) Yes(B) No
Check Left-hand Limit: To determine if h(x) is continuous at x=0, we need to check if the left-hand limit as x approaches 0 from the left (x < 0) is equal to the right-hand limit as x approaches 0 from the right (x≥0), and both of these limits must be equal to the value of the function at x=0.
Calculate Left-hand Limit: First, let's find the left-hand limit of h(x) as x approaches 0 from the left. Since for x < 0, h(x)=e2x, we need to calculate the limit of e2x as x approaches 0 from the left.x→0−limh(x)=x→0−lime2x=e2⋅0=e0=1.
Calculate Right-hand Limit: Next, we need to find the right-hand limit of h(x) as x approaches 0 from the right. For x≥0, h(x)=e5x, so we calculate the limit of e5x as x approaches 0 from the right.x→0+limh(x)=x→0+lime5x=e5⋅0=e0=1.
Check Value at x=0: Now, we need to check the value of the function at x=0. Since x=0 is included in the interval for x≥0, we use the definition of h(x) for x≥0, which is h(x)=e5x.h(0)=e5⋅0=e0=1.
Conclusion: Since the left-hand limit as x approaches 0, the right-hand limit as x approaches 0, and the value of the function at x=0 are all equal to 1, we can conclude that h(x) is continuous at x=0.
