To determine which of the following limits is equal to the integral ∫31sin(x^3+2)dx, we need to inspect each option and check if it matches the properties of the definite integral.

Option A: lim(x→∞) ∫^x_3 sin(t^3+2)dt
Option B: lim(x→0) ∫^3x sin(t^3+2)dt
Option C: lim(x→3) ∫^x_0 sin(t^3+2)dt

We can start by analyzing option A: lim(x→∞) ∫^x_3 sin(t^3+2)dt.

Since the lower limit of integration is fixed at 3, as x approaches infinity, the upper limit tends to infinity. Thus, the integral becomes ∫^∞_3 sin(t^3+2)dt.

To evaluate this integral, we need to find its antiderivative. Unfortunately, the sine function does not have a simple antiderivative. Thus, we cannot calculate the value of this integral directly.

Moving on to option B: lim(x→0) ∫^3x sin(t^3+2)dt.

As x approaches 0, the upper limit of integration approaches 0. Thus, the integral becomes ∫^0_0 sin(t^3+2)dt.

Since the limits of integration are the same, this integral evaluates to zero. Therefore, option B is not equal to the given integral.

Finally, let’s consider option C: lim(x→3) ∫^x_0 sin(t^3+2)dt.

As x approaches 3, the upper limit of integration approaches 3. Thus, the integral becomes ∫^3_0 sin(t^3+2)dt.

To evaluate this integral, we can use techniques of integration or a table of integrals to find the antiderivative of sin(t^3+2). Once we have the antiderivative, we can evaluate it at the upper limit (3) and subtract the evaluation at the lower limit (0) to find the definite integral’s value.

Unfortunately, since I cannot see the options for the limits, I cannot compute their values. However, based on the analysis above, option C has the most potential to be equal to the given integral.

In conclusion, based on the provided information, option C: lim(x→3) ∫^x_0 sin(t^3+2)dt, has the highest likelihood of being equal to the integral ∫31sin(x^3+2)dx.
