Answer:
1 real zero; 2 complex zeros
Step-by-step explanation:
A cubic will have 3 zeros. The number of positive and negative real zeros can be determined using Descartes' rule of signs.
There are no sign changes in the coefficients of the function as written, so there are no positive real roots. (+++)
If odd-degree terms have their sign changed, then there is one sign change. (-++) That indicates there is one negative real root.
The remaining two roots will be complex.

A graphing calculator can confirm this.
ANSWER:
Point in original figure (2, -3)
Point in final figure (-3, -2)
STEP-BY-STEP EXPLANATION:
The first thing is to determine the original point of the figure on the graph, which would be:
The rule for 270° counterclockwise rotation is as follows:
We apply it in this case, and the new point would be:
We represent the result on the graph, as follows
