Math Problem Statement
2 A factory produces smartphones, where the daily output Pix) (in units) depends on the number of employees x. The production is modeled by the function:
P(x)=-2x20x60x70x
a) Use ICT to draw the graph of P(x).
b) Determine the practical domain and practical range.
c) Determine the zeros. What do the zeros mean in this context?
d) Draw the value progression.
e) Use the graph and the characteristics you found to determine how many workers should be employed to maximize production.
