Solve the problem using your calculator.Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both tests and the results are shown below. Use a graphing calculator to model the data with a linear function that predicts a student's score on Test B as a function of his or her score on Test A.
A. y = 0.930 - 19.4x
B. y = -0.930 + 19.4x
C. y = -19.4 - 0.930x
D. y = 19.4 + 0.930x
Answer: D

Find the critical point(s) of the function. Then use the second derivative test to classify the nature of each point, if possible. Finally, determine the relative extrema of the function.
?
?
A. 
is the point of maximum, 11 is the relative maximum

is the critical point, it is impossible to determine the relative extrema of the function
C. 
is the point of minimum, -11 is the relative minimum
D. 
is the critical point, the function has neither a relative maximum nor a relative minimum at this point
E. no critical points
