How To: Given a graph of a polynomial function, write a formula for the function. Identify the x-intercepts of the graph to find the factors of the polynomial.

Step 1: Start with the factored form of a polynomial. Step 2: Insert the given zeros and simplify. Step 3: Multiply the factored terms together.

We can easily find the equation of a polynomial from its graph by identifying x-intercept and the sign of the leading coefficient.
