Work Step by Step
a. $f(0)=3,$ $f(-6)=-3$
b. $f(6)=0,$ $f(11)=1$
c. $f(3)$ is positive and it is around 3.5
d. $f(-4)$ is negative and it is around -1
e. $f(x)=0$ for $x \in \{-3, 6,10 \}$
f. $f(x)\gt 0$ for $-3\lt x\lt 5$ and $10\lt x \leq 11$
g. Domain of $f(x)$ is $-6\leq x \leq 11$
h. Range of $f(x)$ is $-3\leq f(x) \leq 4$
i. $x \in \{-3, 6, 10 \}$
j. $f(x)=3$
k. the line $y=\frac{1}{2}$ intersects the graph 3 times.
l. the line $x=5$ intersects the graph 1 time
m. $f(x)=3$ for $x \in \{ 0, 4\}$
n. $f(x)=-2$ for $x \in \{-5, 8 \}$
