Is it allsquaredor all in the square root? A clearer way of writing that would be 4/√(5- x). Use parentheses!

That is equal to . Use the "power rule" (derivative of is and the chain rule.

f(x)= 2x/(x- 2). Use the quotient rule![SIZE=5]

2. f(x) =2x

x - 2

3. f(x) =√x + 2

Again, "power rule" and "chain rule".
