Compute for $f(x)=\frac{1}{x}$. Homework Help ✎

Replace all x's with what is inside the parentheses.

1. $f\left(\frac{1}{2}\right)$

$f\left(\frac{1}{2}\right)=\frac{1}{\frac{1}{2}}$

Multiply the numerator and denominator by 2.

$\frac{1}{\frac{1}{2}}\cdot\frac{2}{2}=\frac{2}{1}$

$f\left(\frac{1}{2}\right)=2$

2. $f\left(\frac{1}{10}\right)$

Refer to part (a).

$f\left(\frac{1}{10}\right)=10$

3. $f(0.01)$

$f\left(0.01\right)=100$

4. $f(0.007)$

$f\left(0.007\right)=\frac{1000}{7}$
