The zeros of these functions be easily found without one.
How to find zeros of a polynomial function using a graphing calculator. The zeros of a polynomial calculator can find all zeros or solution of the polynomial equation p (x) = 0 by setting each factor to 0 and solving for x. Press [2nd] [trace] to access the calculate menu. Then we equate the factors with zero and get the roots of a function.
