all you have to do is to replace x with the one inside your parenthesis..

for example, from your function, if i am looking for f(1), then it is equal to (1)^2 - 7(1) + 10 = 4.. now, can you do for your question?

if it is f(a-2), then just like the one above, just replace x with a-2.. Ü - Nov 9th 2007, 06:52 AMtopsquark
