Chapter 2: Q.27 (page 198)

Suppose g(x), h(x), and j(x) are differentiable functions with
values of the function and its derivative given in the following table:
$i f f (x) = \frac{3 h (x)}{g (x) + j (x)}, f i n d f' (0) .$

Short Answer

Expert verified

The value of $f' (0)$ is 162

Step by step solution

Step1. Given information

Values of the function and its derivative given.

We have to find out the values of $f' (0)$

Step 2. Differentiate using the quotient rule

$The quotient rule : If f and g are functions and both f and g are differentiable, then quotient rule {(\frac{f}{g})}^{'} (x) = \frac{f (x)' g (x) 鈭� f (x) g (x)'}{(g {(x))}^{2}} Let f (x) = 3 h (x) g (x) = g (x) + j (x) when we apply quotient rule then fiven function f' (x) = \frac{3 h' (x) (g (x) + j (x)) - 3 h (x) (g' (x) + j' (x))}{{(g (x) + j (x))}^{2}} then, f' (0) = \frac{3 h' (0) (g (0) + j (0)) - 3 h (0) (g' (0) + j' (0))}{{(g (0) + j (0))}^{2}} from the given table we get values of h' (0) = 3, g (0) = 2, j (0) = 0, g' (0) = - 2 . j' (0) = - 2 and h (0) = 3 Substitute these values in f' (0), then we get f' (0) = \frac{3 脳 3 (2 + 0) - 3 脳 3 (- 2 - 2)}{{(2 + 0)}^{2}} = \frac{18 + 36}{4} = 162$
