Finding the domain of an Integral












2














I'm trying to figure out what the domain of this function is.



enter image description here



I was thinking that the domain could be the maximum and minimum amounts of area that is accumulated, but I feel like that's the range of the function rather than the domain. Could anyone point me in the right direction to solve this question?

          From the figure we see that the limit of integration is:



          $$
          0le 2x-1 le 6
          $$



          because the function $f(t)$ is:
          $$
          f(t)=begin{cases}
          sqrt{4-(t-2)^2} quad for quad 0le t le 4\
          sqrt{}1-(t-5)^2 quad for quad 4le t le 6
          end{cases}
          $$



          from which you can find the domain of the function: $[frac{1}{2},frac{7}{2}]$.



          And , as you say, the range is the interval between the minimum and maximum values of the area: $[0,2pi]$.
