Write two expressions to create two new number machines that will produce the same output for any input.
Expression 1:
Let's create a number machine that doubles any input. To do this, we can simply write the expression: 2x. No matter what value of x we input into this expression, it will always double that value.
Expression 2:
Now, let's create another number machine that squares any input. The expression for this machine would be: x^2. No matter what value of x we input into this expression, it will always give us the square of that value.
