Use the algebraic procedure explained in section 8.9 in your book to find the derivative of f(x)=1/x. Use h for the small number
Triss [41]

Answer:

By definition, the derivative of f(x) is

lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}

Let's use the definition for f(x)=\frac{1}{x}

lim_{h\rightarrow 0} \frac{\frac{1}{x+h}-\frac{1}{x}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{x-(x+h)}{x(x+h)}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{(-1)h}{x^2+xh}}{h}=\\lim_{h\rightarrow 0} \frac{(-1)h}{h(x^2+xh)}=\\lim_{h\rightarrow 0} \frac{-1}{x^2+xh)}=\frac{-1}{x^2+x*0}=\frac{-1}{x^2}

Then, f'(x)=\frac{-1}{x^2}

Find The Value Of x ?
slega [8]

<u>Answer</u>:

1) x  = -1  ||     2) x = 10

<u>Explanation</u>:

1)

→ \log _3\left(\frac{1}{3}\right)=x

→ \frac{1}{3}  = 3^x

→ 3^{-1} = 3^x

→ x  = -1

2)

→ \log _3\left(x-1\right)=2

→ x - 1 = 3^2

→ x -1 = 9

→ x = 9 +1

→ x = 10
