Q. 6 Suppose that f聽is defined for x... [FREE SOLUTION]

Chapter 3: Q. 6 (page 247)

Suppose that $f$ is defined for $x = 0$ and differentiable everywhere except at $x = 0$ and $x = 1$ , and that $f' (x) = 0$ only at $x$ = 卤2. List all the critical points of f and sketch a possible graph of $f$ .

Short Answer

Expert verified

$f (x) = 0.2 x^{5} 鈭� 0.25 x^{4} 鈭� 1.33 x^{3} 鈭� 2 x^{2}$

Step by step solution

Step1. Given Information

$The function is defined for x 鈮� 0 and is differentiable at all points except at x = 0 and x = 1 and that f^{鈥�} (x) = 0 only at x = 卤 2$

Step 2. Calculations

$The critical points of the function, therefore will be x = 鈭� 2; x = 0; x = 1; x = 2 Therefore, the differentiation of the function will be f^{鈥�} (x) = x (x + 2) (x 鈭� 2) (x 鈭� 1) The graph can be drawn as$

$Therefore, the function is f (x) = 0.2 x^{5} 鈭� 0.25 x^{4} 鈭� 1.33 x^{3} 鈭� 2 x^{2}$
