Answer:
Think of inverse function as reversing something you’ve done. For example, you’re writing a sentence (producing a sentence is similar to the output/result of a function) and then you change your mind and decide you don’t need your last sentence. You would just do CTRL + Z in some editor to cancel this sentence. The CTRL + Z function will take your last sentence as input and return your original text as ouput.
This is also how encryption/decryption work: you give a plain text to an encryption algorithm (here the plain text is the input, like a function variable) and it produces a ciphertext as output. Then you send the encrypted text to someone else. When the receipient gets the encrypted text he will just use a decryption algorithm which is the function inverting the ciphertext back to the original plain text.
