Use the graph of the polynomial function to find the factored form of the related polynomial. Assume it has no constant factor.

(x-1)(x-9) here your x intercepts are (1,0) and (9,0). So you’ll have x-1=0 and x-9=0. Given that idea we can multiply those to come up with the quadratic function. The only one that fits this criteria is (x-1)(x-9)

The answer is
