Problem
What is the maximum number of real zeros for the polynomial \(f(x) = 7x^5 - 3x^4 + 9x^3 - 5x^2 + 2x - 8\)?
Solution
Step 1 ：The maximum number of real zeros for a polynomial is given by the degree of the polynomial.
Step 2 ：In this case, the degree of the polynomial is 5, as the highest power of \(x\) is 5.
