Question

A (b) Use the definition to find a formula for $f'.$ Let $f(x) = x + \frac{1}{x}$. (a) Use superposition of $x$ and $\frac{1}{x}$ to sketch the graph of $f$ on the first set of axes below. Then sketch the graph of $f'$ on the second set of axes. (c) Use superposition to sketch the graph of $f'$ from the formula you found in part (b), and check that it agrees with your graph of $f'$ in part (a).

Let $f(x) = x + \frac{1}{x}$.
(a) Use superposition of $x$ and $\frac{1}{x}$ to sketch the graph of $f$ on the first set of axes
below. Then
sketch the graph of $f'$ on the second set of axes.
(c) Use superposition to sketch the graph of $f'$ from the formula you found in part (b), and check
that it agrees with your graph of $f'$ in part (a).

(b) Use the definition to find a formula for f'.
Let f(x) = x + (1)/(x).
(a) Use superposition of x and (1)/(x) to sketch the graph of f on the first set of axes
below. Then
sketch the graph of f' on the second set of axes.
(c) Use superposition to sketch the graph of f' from the formula you found in part (b), and check
that it agrees with your graph of f' in part (a).

(b) Use the definition to find a formula for f^('). A Letf (x)=x+(1)/(x). (a) Use superposition of x and (1)/(x) to sketch the graph of f on the first set of axes below. Then sketch the graph of f^(') on the second set of axes. (c) Use superposition to sketch the graph of f^(') from the formula you found in part (b), and check that it agrees with your graph of f^(') in part (a). (b) Use the definition to find a formula for f' Letf(x)=x+1/x. below.Then (a) Use superposition of x and 1/x to sketch the graph of f on the first set of axes sketch the graph of f' on the second set of axes (c) Use superposition to sketch the graph of f' from the formula you found in part (b), and check that it agrees with your graph of fin part (a
