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.
Less than
Neither of the two are one-to-one
No. The inverse of an exponential function is a logarithmic function.
-6 is a number, not a function and so there is not an inverse function.
-51
No. It has a discontinuity at every integer value.
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.
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.
Less than
they are inverse functions
Neither of the two are one-to-one
yes
No, it is not. 3/5 is rational and its multiplicative inverse is 5/3 which is not an integer.
No, it does not.
The inverse of the inverse is the original function, so that the product of the two functions is equivalent to the identity function on the appropriate domain. The domain of a function is the range of the inverse function. The range of a function is the domain of the inverse function.
No. The inverse of an exponential function is a logarithmic function.
