Determine a quadratic function f(x) = ax^2 + bx + c such that the maximum value of the function is 2 and the graph of the function has x-intercepts of 3 and 5.
A) f(x) = x^2 − 8x + 15
B) f(x) = 2(x^2 − 8x + 15)
C) f(x) = −2(x^2 − 8x + 15)
D) f(x) = −2(x^2 − 8x − 15)

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
