Question 5 Find all zeros of the function $f(x)=9 x^{3}-18 x^{2}-67 x-20$. Enter the zeros separated by commas. Question Help: Video

Step 1 ：To find the zeros of the function, we need to solve the equation \(f(x) = 0\). This means we need to solve the cubic equation \(9x^3 - 18x^2 - 67x - 20 = 0\).

Step 2 ：The zeros of the function are \(-5/3\), \(-1/3\), and \(4\).

Step 3 ：\(\boxed{-5/3, -1/3, 4}\)
