Linear

Select a Value

Linear

Quadratic, f(x) = x2 – 5x - 2

Exponential, Linear, y = 2x + 4, f(x) = 3.47

y = 2x + 4, Exponential

f(x) = x2 – 5x – 2, Linear

f(x) = 3.4"

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.
