The graph of a rational function $f(x)=\frac{N(x)}{D(x)}$is shown below. Determine which of the statements about the function is false. Justify your answer.

(a) When $x=1$, $D(x)=0$.

(b) The degree of $N(x)$is equal to the degree of $D(x)$.

(c) The ratio of the leading coefficients of $N(x)$and $D(x)$is 1.
