An escalator lifts people to the second floor of a building, 28 ft
above the first floor. the escalator rises at a 30° angle. to the
nearest foot, how far does a person travel from the bottom to
the top of the escalator?
28 ft
300
a person travels
it

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

8496 cars

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
