The function given is:

$f(x) = -x^5 + 10x^4 - 12x^3 + 14x^2 - 7x - 3$

To determine the number of real and imaginary zeros, we can use the following steps:

Step 1: Degree of the Polynomial

The degree of the polynomial is 5 (because the highest power of $x$ is 5). This means that the total number of real and complex (imaginary) zeros will add up to 5, according to the Fundamental Theorem of Algebra.

Step 2: Real Zeros from the Graph

To determine how many real zeros the function has, we analyze the graph of the function. Real zeros correspond to the x-values where the graph intersects the x-axis. If the graph touches or crosses the x-axis at a point, there is a real zero at that point.

• If the graph crosses the x-axis, that is a real zero of odd multiplicity.
• If the graph touches but does not cross the x-axis, that is a real zero of even multiplicity.

Step 3: Imaginary Zeros

The remaining zeros (out of the 5 total) that do not appear as real zeros on the graph are imaginary (complex) zeros. Imaginary zeros always come in conjugate pairs, so there will be an even number of them.

Conclusion:

From the graph, let's assume you observe:

• $n$ real zeros (where the graph intersects the x-axis).
• The remaining $5 - n$ zeros will be imaginary.

Based on this information, if you provide details from the graph (e.g., how many intersections with the x-axis you see), I can finalize the number of real and imaginary zeros.

Would you like to describe or upload the graph for further clarification?

Here are 5 related questions you might consider:

1. What is the multiplicity of a real zero when the graph touches the x-axis but doesn’t cross it?
2. How do complex zeros appear when factoring a polynomial with imaginary numbers?
3. What are the rules for determining the degree of a polynomial and its relationship to zeros?
4. How can Descartes' Rule of Signs help predict the number of positive and negative real zeros?
5. Can all polynomials with real coefficients have an odd number of real zeros?

Tip: The Fundamental Theorem of Algebra guarantees that a degree $n$ polynomial will have exactly $n$ roots (real or complex), including multiplicities.
