1.	Let h(x) = f_(1)(x) + f_(2) (x) + f_(3)(x)+...+f(n)(x), where f_(1)(x), f_(2)(x),f_(3)(x),....,f_(n)(x) are real valued functions of x. Statement I f(x) = \|cos\|x\|\| + cos^(-1)("sgn x")+\|"In x"\| is not differentiable at 3 points in (0, 2pi) Statement II Exactly one function, is f_(i) (x), i = 1, 2,...,n is not differentiable and the rest of the function is differentiable at x = a makes h(x) not differentiable at x = a.

A poor , frustrated artist named Fresco created a plan to make money. He collected trash, repurposed it into sculptures, then asked various celebrities to write and paint on these trash objects, which he then sold on his own as modern high art. The chart below separately showsthe cost and revenue of his plan. The linear cost function, C(x) , represents the total money spent to make and market the art , while the linear revenue function, R(x) , shows the amount of money he has made in sculpture sales. Fresco initially spent money promoting the project in the media . He also had to pay the celebrities to participate . After 6 months , Fresco had created and sold x number of trash sculptures and finally broke even : he hadn't made or lost any money . How many sculptures did Fresco sell in his first 6 months of the project ?

The linear cost function, C(x) , represents the total money spent to make and market the art , while the linear revenue function, R(x) , shows the amount of money he has made in sculpture sales. The cost function in the chart is determined by a constant production cost per sculpture - in this case, the amount Fresco pays each celebrity to participate - as well as a fixed cost , or the initial cost of promoting the project . What is the fixed cost of Fresco's trash sculpture project ?
