This has been a question i have been trying to figure out,
question:
the function f(x)=250x models the maximum number of songs that can be stored on an mp3 player with a capacity of x gigabytes. find the inverse function f-1(x), and explain what it represents in this situation.

This function implies the maximum number of gigabytes of an MP3 player required to store x number of songs.

Step-by-step explanation:

The function f(x)=250x models the maximum number of songs that can be stored on an MP3 player with a capacity of x gigabytes.

Now, the inverse function of the above function is given by

This function implies the maximum number of gigabytes of an MP3 player required to store x number of songs. (Answer)

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
