100 POINTS A salesperson has 50 shirts to sell and must sell a minimum of 20 shirts. The salesperson sells the shirts for $35 each. The amount of money the salesperson makes for selling x shirts is represented by a function. f(x)=35x What is the practical range of the function? all real numbers all multiples of 35 between 700 and 1750, inclusive all integers from 20 to 50, inclusive all multiples of 35 between 0 and 1750, inclusive

danf that a long quiestion but i think it d

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)
