The cost function is an illustration of an exponential growth function, and as such the price of product A is increasing
The cost function of product A is given as:
[tex]C(x) = 72(1.25)^x[/tex]
An exponential function is represented as:
[tex]C(x) =ab^x[/tex]
Where b is the rate of the function.
When b exceeds 1, then the function represents growth and the value of the function increases.
Hence, the price of product A is increasing
