How can i do better on my test? my daily work is easy enough but i tend not to test well

You can study:)

Do study cards, look up worksheets,
Make notes,etc.

Some things you can do to do better on a test is make sure you study well, eat well, sleep well, and even exercise well. These can all help your brain flow a bit better to be able to focus better.

I hope I helped somewhat! :)

The correct answer would be the function g(x) increased at a faster rate
