Final answer:
The graph would be a horizontal line at y = 3 across the entire x-axis.
Step-by-step explanation:
The graph of the function with a domain of all real numbers greater than or equal to -2 and a range of all real numbers less than or equal to 3 would be a horizontal line at the y-value of 3. The line would extend indefinitely to the left and right on the x-axis, and would not change its y-value. This is because the function is constant across the entire domain and range, with the y-value always being 3.
