Question
Why would the function f(x)=200(0.25)^x
incorrectly represent the social media platform's user growth?(1 point)

The function decreases instead of increases with weekly growth

Answer 1

The function shows exponential decay because the base 0.25 is less than 1. For growth the base must be greater than 1, so this model decreases instead of increases.

(If the platform grows 25% per week, the correct model would be f(x)=200(1.25)^x.)
