In one of the archaeolgoical excavating sites, the artifact density per 10 liters of sediment was 1.5 suppose you are going to dig up and examine 40 liters of sediment let r =0,1,2,3 be a random variable that represents the number of artifacts found in your 40 liters identify

a negative exponent is translated as follows:

so, we have

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
