Question

what is the domain of this exponential function?${x | x leq 0}$${x | x < 0}$${x | x > 0}$${x | x geq 0}$all real numbers

Explanation:

Step1: Identify domain from graph

Observe the x-values covered by the blue curve: the curve exists only for $x \geq 0$ (includes $x=0$ and all positive x-values).

Step2: Match to option

The set notation for $x \geq 0$ is $\{x \mid x \geq 0\}$.

Answer:

$\{x \mid x \geq 0\}$
