Mr. Lastorka's science class is running experiments with an energy efficient model electric car, As the initial rate of energy delivered to the car, measured in watt, increases, the number of millimeters moved by the car from its starting positions increases exponentially . The results the several trial runs are shown on the scatterplot graph below. Based on the data, the students in Mr . Lastroka's class determine the exact equation involving Watts, x and total distance from start,y. They call the function y=f(x) over the x-axis. He challenges each student to determine the new function and what it would mean from a physics perspective. Four students pairs gave their answers below. Who is correct, and for what reasons?

Answer» CHARLES and Shannon, who identify the new equation as `y=-2^x` and EXPLAIN that the new graph indicates that the car is still moving forward at the same RATE as before Michael and Lauren, who identify and new equations as `y=-2^x` and explain THEAT the new graph indicates the car is now moving in reverse at the same rate as before. Matthew and KAREN, who identify the new equations as `y=-2^x` and explain that the new graph indicates that the car is now moving forward more rapidly than before. Andy and Joanie, who identify the new equation as `y=2^(-x)` and explain that the new graph indicates that the car is no longer moving in any direction. Answer :B

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 ?
