Step-by-step explanation:
We have been given that a polynomial function models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.
In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:
The zeroes of this polynomial occur when either or
.
The equation have no real solutions. Therefore, the only time when the roller coaster is at the ground is at
