please can someone help me

1. For each of the functions below, find where, if anywhere, the function is holomorphic. Be sure to identify any poles, branch cuts, essential singularities, or other failures to be holomorphic. (a) (10 points) h (z) = 22+ 3z -4 (b) (10 points) g(z) = -1 -h(2) = 5ez - 5 23 + 322 - 4z 2. Compute the integrals below, along the specified contours, using any means you choose. (a) (20 points) f h(z) dz - f 24 32_ 4dz, where C is the circle z (b) (10 bonus points) sin(z) dz, . where C is the circle |z) = 1
