Question

Help please :)
The following graph shows a seventh-degree polynomial:

Answer 1

Part 1: List the polynomial’s zeroes with possible multiplicities.
Part 2: Write a possible factored form of the seventh degree function.


I know the zeroes are x- intercepts. But you can only count 4 or 5.
Does that mean there are complex roots?
(x +5) (x + 1) (x - 4) (x - 7)

what are the other 3 roots?
