(a) Find $f\left(0\right)$ and $f\left(-6\right)$.

(b) Find $f\left(6\right)$ and $f\left(11\right)$.

(c) Is $f\left(3\right)$ positive or negative?

(d) Is $f\left(-4\right)$ positive or negative?

(e) For what values of $x$ is $f\left(x\right)\text{ = 0}$?

(f) For what values of $x$ is $f\left(x\right)\text{ > 0}$?

(g) What is the domain of $f$?

(h) What is the range of $f$?

(i) What are the $x\text{-intercepts}$?
