Assume that we have a function f(x) = 3x + 1, and I want to explain what its derivative is. For this purpose, I constructed following sentence:
If you increment the value of variable x by 1, the result of the function is incremented by 3, and this is always constant because of constant slope.
In this sentence, I used the verb "increment" two times, and this sounds to me weird and not proper. Is there a more formal and proper way to express such a situation? I think that some alternative verbs for "increment" are "increase" and maybe "rise", but they are not appropriate candidates to replace the second "increment" in the sentence.
