The expanded form of the number 0.0001 is .
<u>SOLUTION: </u>
Given that, we have to write 0.0001 in expanded form.
Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression.
Now, take the given number 0.0001
As there are no other digits except 0 in front of 1 our work is simplified.
Expanded form will be
Hence, the expanded form of the number 0.0001 is .
<h2>Answer with explanation:</h2>
The given function :
Using completing the squares, we have
[∵
]
(1)
Comparing (1) to the standard vertex form , the vertex of function is at (h,k)=(-1,-4)
For x-intercept, put f(x)=0 in (1), we get
Square root on both sides, we get
∴ x intercepts : x= (-3,0) and (1,0)
For y-intercept put x=0 in (1), we get
∴ y intercept : (0,-3)
