Answer:

The correct option is;

D. The function is positive when x > 0

Explanation:

The reciprocal parent function is of the form;


y = (a)/(x - h) + k

Where;

h = The horizontal translation

k = The vertical translation

a = The orientation of the graph

Therefore, whereby we have, h = 0, k = 0. and a = 1, the equation becomes;


y = (1)/(x - 0) + 0 = (1)/(x)

Therefore, the value of the function y is positive when x > 0 and is negative when x < 0.
