This problem demonstrates how you enter function answers into Edfinity. First enter the function log æ. (If you have not encountered this particular function yet, you will soon. Note that, unlike calculator, log in Edfinity is equivalent to In - the natural logarithm) When entering the function, you should enter log(x), but Edfinity will also accept log x or even logx. Edfinity will accept this or any other function equal to log(x), e.g. log(x) + log(e^x) - It is better to enter log(x) even though Edfinity will also accept log x or even logx because you are less likely to make a mistake. Try entering log(2x) without the parentheses and you may be surprised at what you get. Edfinity will evaluate functions (such as log) before doing anything else, so log 2x means first apply log which gives log(2) and then multiply by x. Try it.
