The graph you uploaded represents a sinusoidal curve, which appears to be a standard sine or cosine function. Let’s analyze the domain and range.

1. Domain: The domain of the sine or cosine function is all real numbers, since the function continues infinitely in both the positive and negative directions along the $x$-axis. $\text{Domain}: (-\infty, \infty)$

2. Range: The range of the sine or cosine function is limited between the maximum and minimum values that the curve reaches on the $y$-axis. From the graph, the curve oscillates between $y = 1$ and $y = -1$. $\text{Range}: [-1, 1]$

So, the domain is all real numbers, and the range is from $-1$ to $1$.
