Final answer:
The function g(n) determines the cropped photo's width by subtracting 5 inches from the original width.
Step-by-step explanation:
The function g(n) represents the cropped photo's width in inches after cropping 5 inches from a photo with width n inches. To determine g(n), we subtract 5 from the given width, so g(n) = n - 5.
For example, if the original width of the photo is 10 inches, the cropped photo's width would be 10 - 5 = 5 inches.
Therefore, the function g(n) determines the cropped photo's width by subtracting 5 inches from the original width.
