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 f(x) is found by evaluating f(0), since the initial value represents the value of the cell phone at the moment of purchase, which is typically at 0 months.
f(0) = -75(0) + 1,200 = 1,200
Therefore, the initial value of the function is 1,200.
Interpretation:
The initial value of the function represents the value of the cell phone at the moment of purchase. In this case, the cell phone's value is $1,200 when it is purchased.
