Inverse Function of Numbers
The question in the image asks us to determine the images by the inverse function of the given numbers. This means we need to find the multiplicative inverse of each number, which is just 1 divided by the number itself.
Here are the inverses:
1. For -4: the inverse is \( \frac{1}{-4} \) or -0.25.
2. For \( \frac{1}{5} \): the inverse is \( \frac{1}{\frac{1}{5}} = 5 \).
3. For \( \frac{10}{5} \): the inverse is \( \frac{1}{\frac{10}{5}} = \frac{1}{2} \) or 0.5.
4. For \( \frac{5}{8} \): the inverse is \( \frac{1}{\frac{5}{8}} = \frac{8}{5} \) or 1.6.
So the images by the inverse function are: -0.25, 5, 0.5, and 1.6.
