If the function f f is a decreasing function on an open interval I I, then the inverse function 1 f 1 f is increasing on this interval. If the functions f f and g g are increasing

It's not going to solve world problems but simple equations it can handle, best math app I use good for any type of students. The explanations are a little trickery to understand at first, but once you get the hang of it, it's really easy.

A great thing to use when studying for an exam. Amazing app, got my F to an A with flying colors, the only reason I passed math classes. Its helped me a lot more than I expected when I initially downloaded it. Whoever made this has helped me along my high school and college career, and for that, i thank you for making such a helpful app (and website).

I needed this for a single reason, solving math problems at work on the fly. I love how its supportive. Its is so helpful to be able to insert the equation, get the answer, and an explanation as to how to arrive at the correct answer without having to wait forever and deal with a bunch or errors.

The intervals where a function is increasing (or decreasing) correspond to the intervals where its derivative is positive (or negative). So if we want to find the intervals where a function

Solve word questions

Math is a way of solving problems by using numbers and equations.

Solve math equations

To solve a math equation, you need to find the value of the variable that makes the equation true.
