Answer
A
Image with description On a coordinate plane, the curve originate on y-axis and passes through (1 comma 1), (4 comma 2),and (8 comma 3) in the first quadrant.
B
Image with description On a coordinate plane, the curve originate on y-axis and passes through (1 comma negative 1) and (4 comma negative 2) in the fourth quadrant.
C
Image with description On a coordinate plane, the curve passes through (negative 3 comma 8), (negative 2 comma 4), (negative 1 comma 2), and (0 comma 1). It approaches to the x-axis as the value of x increases.
D
Image with description On a coordinate plane, the curve passes through (0 comma 1), (1 comma 2), (2 comma 4), and (3 comma 8). It approaches to the x-axis as the value of x decreases.
