Emily practices the piano 25 minutes a day. to identify the total number of minutes she practices, she uses the function rule:
y = 25x. find f (10)

When you are finding f(10), that is like saying find how many minutes she practices if she practices 25 minutes a day for 10 days. To find the answer, first remember that y is the same as saying f(x). So to find f(10), you just have to plug in a 10 where you see an x.

f(10)=25*10
f(10)=250

Hope this helps.

Your answer should be 1/3. i hope i could ! good luck : )

The answer would be 484
