On a coordinate plane, a curved line with a minimum value of (negative 1.25, negative 3.25) and a maximum value of (0.25, negative 1.75), crosses the x-axis at (negative 2.25, 0), and crosses the y-axis at (0, negative 2). The line exits the plane at (negative 2.75, 6) and (1.5, 6).

Question illustration
A
As the x-values go to positive infinity, the function's values go to negative infinity.
B
As the x-values go to zero, the function's values go to positive infinity.
C
As the x-values go to negative infinity, the function's values are equal to zero.
D
As the x-values go to positive infinity, the function's values go to positive infinity.
