Answer:
The choices were typed wrong, but we can find the inverse of each option.
For function the inverse is the same function
, because an inverse of a function is where their composition gives the independent variable as unique result.
If we do that with each function, we have:
; where
and
, we have
So they are inverse.
For its inverse would be
, because
For , its inverse is
, because
For , its inverse is
, because
There you have all inverses. Basically, if their composition results in , that means they are inverse.
Answer with Step-by-step explanation:
Permutation : It is an arrangement of r elements out of n elements.
Combination : it is a selection of r element out of n elements .
Suppose we have a set
S={1,2,3}
If two elements are taken at a time then
Using permutation formula
Total number of outcomes=
Total number of outcomes=
Total number of outcomes=3!=
Using combination formula
Total number of outcomes=
Total number of outcomes=
Hence, total number of outcomes=3
Total number of outcomes determined by permutation have more outcomes.
Because permutation is an arrangement of elements therefore, it consider order of arrangement of element but combination is a selection of elements it does no consider order of elements
Arrangements of two elements out of 3 elements
{1,2},{2,3},{2,1},{3,2},{1,3},{3,1}
By using combination if two elements taken at a time then combination
{1,2},{2,3},{1,3}
