Inverse of a function exists only if it is a Bijection. Bijection=Injection(one to one)+surjection (onto) function.
Both the Greatest Integer Function and the Absolute Value Function are considered Piece-Wise Defined Functions. This implies that the function was put together using parts from other functions.

Neither of the two are one-to-one
No. The inverse of an exponential function is a logarithmic function.

The greatest negative integer is -1. The additive inverse of a number is the value that, when added to the original number, results in zero. Therefore, the additive inverse of -1 is +1.

The greatest integer function, often denoted as ⌊x⌋, gives the largest integer less than or equal to x. For 0.7, the greatest integer is 0, since 0 is the largest integer that is less than or equal to 0.7. Thus, ⌊0.7⌋ = 0.
No. It has a discontinuity at every integer value.
To identify the equation that matches the graph of the greatest integer function, look for the characteristic step-like pattern of the function, which takes on integer values and jumps at each integer. The greatest integer function is typically denoted as ( f(x) = \lfloor x \rfloor ), where ( \lfloor x \rfloor ) represents the greatest integer less than or equal to ( x ). If the graph shows horizontal segments at each integer value until the next integer, it confirms that it represents this function.
The additive inverse of an integer ( x ) is the integer that, when added to ( x ), results in zero. This integer is (-x). For example, the additive inverse of 5 is -5, and the additive inverse of -3 is 3.
Yes, the greatest integer function, often denoted as ⌊x⌋, is many-to-one. This means that multiple input values can produce the same output. For example, both 2.3 and 2.9 yield an output of 2 when passed through the greatest integer function, as both round down to the greatest integer less than or equal to the input. Thus, it is not a one-to-one function.
An inverse integer typically refers to the additive inverse of an integer, which is the number that, when added to the original integer, results in zero. For example, the additive inverse of 5 is -5, as 5 + (-5) = 0. In a broader mathematical context, the term can also refer to the multiplicative inverse, which is a number that, when multiplied by the original integer, results in one; for instance, the multiplicative inverse of 5 is 1/5.
Both the Greatest Integer Function and the Absolute Value Function are considered Piece-Wise Defined Functions. This implies that the function was put together using parts from other functions.

Every integer has its own additive inverse, which is simply the integer multiplied by -1. For example, the additive inverse of 5 is -5, and the additive inverse of -3 is 3. Therefore, all integers, including zero, have their own additive inverses. In summary, any integer ( x ) has an additive inverse of ( -x ).
