Answer:
Because we actually divide by 10 when a number is multiplied by 0.1.
Step-by-step explanation:
Let
be a number.
When we multiply a number by 10:
(One '0' is increased in the number)
For example:
![23 \times 10 = 230](https://tex.z-dn.net/?f=23%20%5Ctimes%2010%20%3D%20230)
Considering a decimal number:
![2.3 \times 10 = 23](https://tex.z-dn.net/?f=2.3%20%5Ctimes%2010%20%3D%2023)
Multiplying a number with 0.1 (which is actually
) means dividing the number by 10.
![23\times 0.1 =23\times \frac{1}{10}=2.3](https://tex.z-dn.net/?f=23%5Ctimes%200.1%20%3D23%5Ctimes%20%5Cfrac%7B1%7D%7B10%7D%3D2.3)
Considering a decimal number:
![2.3 \times 0.1 = 2.3 \times \frac{1}{10} = 0.23](https://tex.z-dn.net/?f=2.3%20%5Ctimes%200.1%20%3D%202.3%20%5Ctimes%20%5Cfrac%7B1%7D%7B10%7D%20%3D%200.23)
<em>Therefore, When multiplying a number by 0.1, move the decimal to the left.</em>
Answer:
![h(x) = \frac{1}{4}x](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5Cfrac%7B1%7D%7B4%7Dx)
Step-by-step explanation:
Suppose h is the inverse of f then
f(x) = y ⇔ h(y) = x
f(x) = y ⇔ 4x = y ⇔ x = y/4
and since x = h(y) then h(y) = y/4
then we can write :
![h(x) = \frac{x}{4}](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5Cfrac%7Bx%7D%7B4%7D)
