Question
the revenue function r(x) and the cost function c(x) for a particular product are given. these functions are valid only for the specified range of values.

find the number of units that must be produced to break even.
upper r(x) = 200 x -2 x squared

c(x) = −x squared + 25x+3100 0 less than or equal to x less than or equal to 100

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.
