\"\"

\

The function rational is \"\".

\

Observe the graph, the x - intercept of the graph of the rational function f(x) is (0, 0).

\

\"\"

\

The function is \"\" and y = 0.

\

\"\"                          (Substitute y = 0)

\

\"\"                                    (Multiply each side by \"\")

\

x = 0                                       (Divide each side by 2)

\

The value of  x = 0 is a x - intercept of the graph of the rational function in part (a).\"\"

\

The value of  x = 0.
