Break-even analysis. Use the revenue function from Problem 70 and the given cost function: R x = x 2 , 000 − 60 x Revenue function C x = 4 , 000 + 500 x C o s t function where x is millions of computers, and C x and R x are in thousands of dollars. Both functions have domain 1 ≤ x ≤ 25 . (A) Sketch a graph of both functions in the same rectangular coordinate system . (B) Find the break-even points. (C) For what values of x will a loss occur? A profit?

Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity
