Use the graph of the polynomial function to find the factored form of the
related polynomial. assume it has no constant factor.
o a. (x - 1)(x-8)
o b. (x - 1)(x+8)
c. (x + 1)(x+8)
o d. (x + 1)(x - 8)

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
