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.
