1. The problem is to identify the key features of a polynomial function. 2. Key features of a polynomial function include its degree, leading coefficient, intercepts (x- and y-intercepts), turning points (extrema), end behavior, and zeros. 3. The degree of the polynomial determines the maximum number of turning points and zeros. 4. The leading coefficient affects the end behavior: if positive, the ends go up for even degree and opposite for odd degree. 5. Intercepts are found by evaluating the function at $x=0$ for the y-intercept and solving $f(x)=0$ for x-intercepts. 6. Turning points are where the function changes direction, found by setting the derivative equal to zero. 7. Zeros are the roots of the polynomial, which can be real or complex. 8. To fully identify these features, the explicit polynomial function is needed. 9. Without a specific polynomial, we cannot calculate exact values but can describe these general features.
