### Subject: US History

Briefly describe the Interstate Commerce Commission of 1887, and the lasting impact it had.

The Interstate Commerce Commission (I.C.C) of 1887 was established to regulate railroads and establish fair trade. The I.C.C was to oversee that railroads establish "reasonable" rates and could not favor shippers. It was intended to help struggling farmers. However the language of the act itself was very weak and lacked the power to enforce the regulations. However this was a step in the right direction as it showed that the U.S government was beginning to take a bigger interest in regulating the economy. The I.C.C gained power and better language during the progressive era.

given the following two functions. h(n) = 4n + 5 g(n) = 3n + 4 Find (h-g)(n)

First we can turn (h-g)(n) into h(n) - g(n) Next we simply plug in the given functions (4n + 5) - (3n + 4) 4n + 5 - 3n - 4 Here we simply distributed the negative n+1 simply add up your like terms ( h - g )(n) = n+1 Simply clean it up and we are all done.
