Final answer:

To find the area of the region between the curves 4xy² = 12 and x = y, we can set up a double integral. The limits of integration are y = 0 and y = ∛3. The area of the region is 3/2.

Step-by-step explanation:

To find the area of the region between the curves 4xy² = 12 and x = y, we can set up a double integral. We need to find the limits of integration first. From the equation x = y, we can substitute y for x in the other equation:

4y(y^2) = 12

Simplifying, we get:

4y^3 = 12

y^3 = 3

From this equation, we can see that y = ∛3 is the upper limit of integration. The lower limit is y = 0 since the region is bounded by the x-axis. The integral to find the area is:

∫[0,∛3] ∫[y,3/y²] dx dy

This integral can be evaluated to find the area of the region, and the answer is option A: 3/2.
