Question

given x=8, substitute x into the function f(x)=9logx to find f(x)

Answer 1

I'd give a medal for the best answer :3

Answer 2

Do exactly what the instruction says. In 9log(x), replace x by 8 and that will be your answer.

Answer 3

alright i got 8.127. hopefully thats the right answer. thanks again!

Answer 4

Sometimes just 9log(8) will be an acceptable answer. Sometimes they expect you to evaluate using a calculator and provide them with a number. So the answer depends on what form they are expecting here.

Answer 5

oh well they wanted my answer to be a decimal and i was told to round it to 3 decimal places.

Answer 6

9log(8) = 8.127809....
If you round to 3 decimal places, it is 8.128 (not 8.127)

Answer 7

oh. well thanks

Answer 8

you are welcome.
