For each of the following determine the points at which the function is not analytic: 1) 1/z - 4 + 5i.
2) iz^3 + 2z/z^2 + 1.
3) 3z - 1/z^2 + z + 6.
4) z^2 (5z^2 - 6z + 1)^-2.

The first one is correct

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
