Question

Suppose you want to crop 4 inches from the right side of a photo you have and then resize the photo by making it 40% of its cropped size. (that is, each side length is 40% of that side length after it was cropped.) if f is the function that inputs the original photo length (in inches) and outputs the cropped photo length (in inches without resizing), write a formula to define f . use x as the input variable.

Answer 1

The function f to define the cropped photo length, after cutting 4 inches from the right side of the photo, is represented by the formula f(x) = x - 4, where x is the original length of the photo.

Step-by-step explanation:

If f is the function that inputs the original photo length (in inches) and outputs the cropped photo length (also in inches), without considering the resizing, the formula would simply be subtracting the inches cropped from the original length. Given that we're cropping 4 inches from the length, the function f(x) that defines the cropped photo's length in terms of the original length x would be:

f(x) = x - 4

This is because cropping 4 inches from the right side of a photo reduces its length by 4 inches, regardless of the original length. Therefore, for any original length x, the cropped length is four inches less.
