Question

here is the graph of $g(r)$.
write a compound inequality to describe the domain.
$-1 \leq r \leq 15$
write a compound inequality to describe the range.
$1 \leq r \leq 8$
submit

Explanation:

Step1: Identify domain from graph

The graph's leftmost point has $r=-1$ (closed dot, included), rightmost has $r=15$ (closed dot, included).
Domain: $-1 \leq r \leq 15$

Step2: Identify range from graph

The lowest point of the graph has a $g(r)$ value of 1, the highest has a $g(r)$ value of 8 (both closed dots, included).
Range: $1 \leq g(r) \leq 8$

Answer:

Domain: $\boldsymbol{-1 \leq r \leq 15}$
Range: $\boldsymbol{1 \leq g(r) \leq 8}$
