Answer

4 real zeros (with one zero of multiplicity 2) and no imaginary zeros.

Work Step by Step

Step 1. Based on the graph, we can identify that the curve crosses the x-axis 3 times, given 3 real zeros. Step 2. We can identify that the curve touches and turns around (right side), indicating a zero with a multiplicity of 2. Step 3. We have counted 4 real zeros (with one zero of multiplicity 2) and no imaginary zeros.
