The Morris family and the Thompson family each used their sprinklers last summer. The water output rate for the Morris family's sprinkler was 15 L per hour. The water output rate for the Thompson family's sprinkler was 35 L per hour. The families used their sprinklers for a combined total of 55 hours, resulting in a total water output of 1225 L .

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)
