How can you tell if a graph is a function
Web22 de jan. de 2024 · Then you know what intervalls are interesting. Those intervalls are a finite number for most excercises you encounter, or have a very easy to recognize pattern (like sin(x)-cos(x) ). Then check with values inside those intervalls, wether f(x)>g(x) or vice versa. Can you explain why this works? Web29 de mar. de 2024 · 4. Compare the two functions. For each example that you are testing, compare the simplified version of f (-x) with the original f (x). Line up the terms with each other for easy comparison, and compare the signs of all terms. [4] If the two results are the same, then f (x)=f (-x), and the original function is even.

Web21 de jul. de 2016 · 1. I need to be able to identify if a function is indifferentiable at any point. The common way to do that is to actually determine the derivative and inspect it for singularities. This is generally easy with elementary functions.
