question 49

Essay

Solve the problem.
-Given R(x)=x3+7x22xR ( x ) = x ^ { 3 } + 7 x ^ { 2 } - 2 x and C(x)=2x2+24C ( x ) = 2 x ^ { 2 } + 24 where xx represents the number of items produced in hundreds, R(x)R( \mathrm { x } ) and C(x)\mathrm { C } ( \mathrm { x } ) represent revenue and cost in thousands of dollars. where x represents the number of items produced in hundreds, R(x)
a)Find P(x).
b)Find P(0), R(0), and C(0)and interpret each of these.
c)Find the break-even point (value wherehere P(x)=0) if 0<x<4P ( x ) = 0 ) \text { if } 0 < x < 4 \text {. } d)For what values of x ist values of x is P(x)>0 if 0<x<4?\mathrm { P } ( \mathrm { x } ) > 0 \text { if } 0 < x < 4 ? e)For what values of x ist values of x is P(x)<0 if 0<x<4?P ( x ) < 0 \text { if } 0 < x < 4 ? f)Interpret the results from parts d)and e).
