 Question 281944: if f(x) = , then the derivative of f evaluated at x=1 equals: a) 2 b) 4 c) 5 d) 6 My guess is D (6). I graphed the function. I used my table command with the change in x being .1 Then I found the value of the function at 1.9 and 2.1 Since the derivative represents the slope at a particular x-value, I found the slope around 2. The slope was 5.9595, which is close to 6. I tried to take the derivative of this function, but I got lost. Here's what I tried: = = then the functional value at 1 is 30/6 = 5.
