Write a piecewise-defined function to model the monthly cost C(x) (in $) as a function of the number of minutes used x for the month. Sketch a graph of the function. 2) A cell phone plan charges $ 45.75 per month, plus $ 9.55 in taxes, plus $0.35 per minute for calls beyond the 500-min monthly limit. 2)
