The function f(x)=−75x+1,200 represents the value of your cell phone x months after you purchase it. Identify and interpret the initial value of the function
The initial value of the function is the value of your cell phone when you first purchase it, which is represented by f(0).
In this case, when x is 0, the function becomes f(0) = -75(0) + 1,200 = 1,200.
Therefore, the initial value of the function is $1,200.
This means that when you first purchase your cell phone, it is worth $1,200.
