Question

find the domain and range of the relation. write in interval notation

Explanation:

Step1: Identify all x-values (domain)

The x-coordinates of the vertices are $-2$, $8$, and $10$. The relation covers all x-values from the smallest to the largest.

Step2: Write domain in interval notation

The minimum x-value is $-2$, maximum is $10$. So domain is $[-2, 10]$.

Step3: Identify all y-values (range)

The y-coordinates of the vertices are $-9$, $-2$, and $-10$. The relation covers all y-values from the smallest to the largest.

Step4: Write range in interval notation

The minimum y-value is $-10$, maximum is $-2$. So range is $[-10, -2]$.

Answer:

Domain: $[-2, 10]$
Range: $[-10, -2]$
