Question

what is the domain and range of the function below? the domain is the range is

Explanation:

Step1: Identify domain (x-values)

The graph extends infinitely left and right, so all real numbers are valid x-values.
Domain: $\{x \mid x \in \mathbb{R}\}$

Step2: Identify range (y-values)

The graph has a minimum y-value of -3, and extends upward infinitely.
Range: $\{y \mid y \geq -3\}$

Answer:

The domain is $\boldsymbol{\{x \mid x \in \mathbb{R}\}}$
The range is $\boldsymbol{\{y \mid y \geq -3\}}$
