Holistic Rubric for 4-Point Reasoning Constructed Response Items

Sample Top Score Response

Part A

A quadratic equation with real coefficients that has x = − 5 i as a solution must also have x = 5 i as a solution. One such equation is ( x − 5 i ) ( x + 5 i ) = 0 , which is equivalent to x 2 + 25 = 0 .

Part B

There is no quadratic equation with real coefficients that has x = − 5 i as its only solution. If the only solution is x = − 5 i , then the quadratic equation is a multiple of ( x + 5 i ) 2 = 0 , which is equivalent to x 2 + 10 i x − 25 = 0 , and that equation cannot be equivalent to one with real coefficients because 10 i − 25 is not a real number.

An estimate for the number of members in the 4 t h month is 211 . An estimate for the number of members in the 8 t h month is 273 .

Average rate of change: 273 − 211 8 − 4 = 62 4 = 15 1 2 members per month

The expression 280 ( 0.76 ) t approaches zero as t increases. So, 300 − 280 ( 0.76 ) t approaches 300 as t increases. Therefore, 300 is the maximum number of members.

Part A

The function fx=81.670.67x models the data. An exponential function was chosen because the data seems to decrease rapidly at first, then level off a bit.

The constant 81.67 represents the box office revenue, in million dollars, predicted by the function 0 weeks after the movie opened, that is, during the movie’s opening week.

The constant 0.67 means that the revenue is decreasing on average by 1-0.67=0.33 or 33% each week.

Part B

100,000 is 0.1 million, so the time when the function has a value less than 0.1 should be determined. By graphing y=81.670.67x and y=0.1 on the same graph, it can be seen that the least number of weeks after the movie opened when the function value is less than 0.1 is 17.
