Consider the graph of the polynomial function p(x)=(x-1)(x+2)(x+5)

The graph is first increasing then decreasing to right.

Step-by-step explanation:

Given : The polynomial function

To find : Consider the graph of the polynomial function and the graph is ?

Solution :

First we graph the given polynomial function,

which cut the x-axis at 1,-2,-5.

Refer the attached figure below.

The graph is first increasing to the point (-3.7,10.3) then decreasing to point (-0.268,-10.392) then increasing to infinity.

Therefore, The graph is first increasing then decreasing to right.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
