The Sumner Museum had collected family photos of town residents for more than a century. The museum director reported that between 1890 and 1900, the average family photo had 5 family members in it. They had 163 family photos from that decade. About how many people would you expect to see in all of the photos from the decade 1890-1900?

step-by-step explanation:

for volume, add base x height x width

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)

it would have to be 3/0
