To analyze the tile pattern and write a function for it, we first need to observe the relationship between the image number (x) and the number of tiles (y) in each configuration.

Let's assume the image number corresponds to the configuration:

  • Image 1: Number of tiles = a
  • Image 2: Number of tiles = b
  • Image 3: Number of tiles = c
  • Image 4: Number of tiles = d

From the information you have, identify the number of tiles in each configuration, then find the pattern.

  1. Identify the slope of the function, which is the change in the number of tiles (y) for each increase in the image number (x). This can be calculated as: \[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} \] for any two images.

  2. Find the y-intercept, which is the number of tiles when x = 0. If your sequence starts at image number 1 with a certain number of tiles, you can extrapolate backwards to find the y-intercept.

Using these two pieces of information you can write the function in slope-intercept form \( y = mx + b \), where:

  • m is the slope (change in y for a change in x),
  • b is the y-intercept (value of y when x = 0).

If you provide the number of tiles for each configuration (images 1-4), I can help you calculate the function. Otherwise, you can follow these steps using the specific y-values you have from the tile images.
