The initial value of the function is the value of the cell phone when you first purchase it, which is represented by the y-intercept of the function. In this case, the function is F(X) = -75X + 1200, and the y-intercept is 1200.
Interpreting this, it means that when you first purchase the cell phone, its value is $1200. This is the starting point from which the value of the cell phone decreases at a rate of $75 per month.
