## How To Find Zeros Of A Polynomial Function Using A Graphing Calculator Ideas

How To Find Zeros Of A Polynomial Function Using A Graphing Calculator Ideas. If the remainder is 0, the candidate is a zero. Now, let’s find the zeros, maximum, and minimum of the function from the previous problem above.

If there are any functions in this window, clear them out by highlighting the = sign and pressing enter. This is easier to see if the polynomial is written in factored form. Then, we will use the graphing calculator to find the zeros, maximums and minimums.

### This Precalculus Video Tutorial Provides A Basic Introduction Into The Rational Zero Theorem.

Now, let’s find the zeros, maximum, and minimum of the function from the previous problem above. Another way to find the intercepts of a polynomial function is to graph the function and identify the points at which the graph crosses the axis. Let's graph using a graphing calculator.

### This Is Easier To See If The Polynomial Is Written In Factored Form.

If the remainder is 0, the candidate is a zero. Analyzing graphs using a graphing calculator enter the function into the calculator (hit y= then type). Suppose the given polynomial is f(x)=2x+1 and we have to find the zero of the polynomial.

### Then We Solve The Equation.

Find the zeros of the polynomial graphed below. For algebra 2 or precalculus. (look at the table to see what the min and max values of x and y should be.) use the calc functions ( 2nd trace ) to find zeros:
