Plzzz !
nico and fleur are each designing a fictional bike for their business science class. nico determines, through research, that the marginal of producing a bike is

cz(x)-0.0005x2+0.07x+50, for which c1(x) is the cost for manufacturing her bikes could be modeled by cz(x)=25x+62.5. assuming each student's fictional company starts "manufacturing" bikes at the same time answer the following questions.

-what is the domain and range of nico's functions? explain what the domain and range represent. do all of the values make sense in this situation? why or why not?

-what are the x- and y- intercepts of nico's function? explain what each intercept represents.

-is the linear function you created positive or negative? explain.

-what are the solutions or solution to the system of equations created? explain what it or they represent.
