The transformation denoted by Af(X) indicates a vertical stretch or squeeze of the graph of f(x) based on the value of the constant A.

When A is greater than 1, this results in a vertical stretch, as the output values of f(x) are multiplied by a factor larger than one. This means that all points on the graph will be moved further away from the x-axis, effectively making the graph "taller."

Conversely, when A is between 0 and 1, Af(X) leads to a vertical squeeze. In this case, the output values are multiplied by a factor less than one, which causes the graph to be compressed towards the x-axis, making it "shorter."

Therefore, the main focus of Af(X) is how it modifies the y-values of f(x) and, as such, it directly influences the vertical characteristics of the graph while leaving the horizontal position unaffected. This is what qualifies the correct answer as a vertical stretch or squeeze.
