SAT question 1ee962ec (Nonlinear Functions)

Question

Scientists recorded data about the ocean water levels at a certain location over a period of 6 hours. The graph shown models the data, where y = 0 represents sea level. Which table gives values of x and their corresponding values of y based on the model?

College Board · Accepted Answer

The correct answer is C. Choice C is correct. Each point ( x , y ) on the graph represents an elapsed time x , in hours, and the corresponding ocean water level y , in feet, at a certain location based on the model. The graph shown passes through the points ( 0 , 0 ) , ( 3 , - 12 ) , and ( 6 , 0 ) . Thus, the table in choice C gives the values of x and their corresponding values of y based on the model.

Note: The table lists the three points the parabola passes through.

$x$	$y$
$0$	$- 12$
$0$	$3$
$3$	$6$

$x$	$y$
$0$	$0$
$3$	$12$
$0$	$- 6$

$x$	$y$
$0$	$0$
$3$	$- 12$
$6$	$0$

$x$	$y$
$0$	$0$
$12$	$3$
$- 6$	$0$
