A graph plots two points at (negative 7, 8) and (negative 2, negative 9) on the x y coordinate plane. A diagonal curve connects both points.
What is the range of the function shown on the graph above?
A. -2≤y≤-7
B. -8≤y≤8
C. -7≤y≤-2
D. -9≤y≤8
The range of a function represents all possible y-values that the function can take. In this case, the graph shows two points, (-7, 8) and (-2, -9), and a diagonal curve connecting them.
From the graph, we can see that the lowest y-value is -9 and the highest y-value is 8. Therefore, the range of the function is -9≤y≤8.
So, the correct answer is D. -9≤y≤8.
