The graph below shows two linear functions.
which explanation could be used to verify whether the
functions are inverses?
neither of the lines is parallel to the line y=x, therefore,
the functions are inverses of each other
neither of the lines is parallel to the line y=x, therefore,
the functions are not inverses of each other.
the point of intersection of the two functions is not on
the line y=x, therefore, the functions are inverses of
each other
the point of intersection of the two functions is not on
the line y=x, therefore, the functions are not inverses of
each other

Step-by-step explanation:

Graphically

1)Firstly, It's necessary to have the graph attached or at least the functions. After some searches, this question was not found.

2) A function has its invertibility checked by simply passing on the horizontal line test. In other words, if the function graph is hit only once then its inverse, is a an inverse function.

3)This is because, only one-to-one functions, i.e. injective functions are invertible.

In this case we have a pair of functions:

1) Check individual functions

2) Pass a (horizontal) line parallel to the x-axis

3) if this line hits only once then it is invertible.

Algebraically:

If you want it algebraically do it f(g(x))

If f(g(x))=g(f(x)) they are invertible.

The point of intersection of the two functions is not on the line y = x; therefore, the functions are not inverses of each other.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
