Find the zeros of the function. f(x) = 9x^3 + 18 x^2 - 135x

1 answer:

6 0

Where f(x)=0 is the zeros of the funciton

factor out the common factor of all of them which is 9x
f(x)=9x(x^2+2x-15)
what 2 numbers multiply to get -15 and add to get 2?
5 adn -3

f(x)=(9x)(x+5)(x-3)
set to zero
9x=0
x=0

x+5=0
x=-5

x-3=0
x=3

zeroes at x=-5, 0,3

Answer:the relative ages of the rocks exposed in the circle cliff area are given below.

1. older rocks are exposed in the center and younger rocks in the flanking flatirons.

2. younger rocks are exposed in the center and older rocks in the flanking flatirons.

Step-by-step explanation: this is because whenever older rocks are exposed in circle cliffs, exposure occur at the center while younger rocks will be exposed in the flanking flatirons at this time.

2. But when younger rocks are exposed in contrast to the older rocks, these younger rocks are exposed at the center while the older ones receive exposure at the flanking flatirons.

Note that both cases interchange, exposure of a particular rock occur at the center and the next category of rock receive theirs at flanking flatirons.
