Answer: No, the friend is correct. In any function, each input value can only lead to one output value. When you input 3 for the x-values, you would get two output values because 3 is included in both equations. To fix this, you need to have the 3 not included in one of the equations.
For example, you could say or
because the input value of 3 would not be included twice.
If you look at the attached screenshot, you will see that if you keep your friend's function, inputting 3 will result in two outputs of 4 and -3, so therefore, cannot represent a piecewise function.
Given:
Volume of Large cube = 1 cubic unit
Volume of small cube = cubic unit
To find:
The difference between the edge length of the large cube and the edge length of the small cube.
Solution:
Let the edges of large and small cubes are and
respectively.
We know that, volume of a cube is
Volume of Large cube = 1 cubic unit
Taking cube root on both sides, we get
So, edge of large cube is 1 unit.
Volume of small cube = cubic unit
Taking cube root on both sides, we get
So, edge of large cube is unit.
Now, difference between them is
Therefore, the difference between the edge length of the large cube and the edge length of the small cube is unit.
