Find the equation of a cubic polynomial with zeros 1 and 3i

Given the graph below state whether or not the relation is a function, and give the domain and range.

Secant ac and bd intersect at point e inside f what is the measure of aed if measurements cd equals 30 a b is 50 and cb is 170

Ok a point t on a segment with endpoints d(1, 4) and f(7, 1) partitions the segment in a 2: 1 ratio. find t. you must show all work to receive credit.
