MAXImum [283]
Hey there, Lets solve your question together 

Question - <span>What is 400 in Expanded form ? 
</span>
We know that expanded form is a spread out way to write a number by showing the value of each individual digit that contributes<span> to make the full number. 
</span>
Lets use an example to show expanded form

Number - 4,265 

= 4 x 1,000 + 2 x 100 + 6 x 10 + 5 x 1 

Now lets solve for the number 400 in expanded form. 

The number "4" is in the hundreds place 

The number "0" is in the tenths<span> place 
</span>
<span>The number "0" is in the One's place 

</span>Therefore 400 in expanded form is 400+00+0. 
 
<span>          Hope this helps </span>

aalyn [17]

Answer:

\large\boxed{f^{-1}(x)=h(x)=\dfrac{1}{4}x}

Step-by-step explanation:

f(x)=4x\to y=4x\\\\\text{exchange}\ x\ \text{to}\ y\to x=4y\\\\\text{solve for}\ y:\\\\4y=x\qquad\text{divide both sides by 4}\\\\\dfrac{4y}{4}=\dfrac{x}{4}\\\\y=\dfrac{1}{4}x
