Answer:the answer to this is 0.009
Step-by-step explanation:
Answer:
To find the inverse of:

Set the function to y:

Rearrange to make x the subject:






Swap x and y:

Change y to the inverse of the function sign:


Rewrite g(x) as a fraction:





Therefore, as the inverse of f(x) ≠ g(x), the functions are NOT inverses of each other
THe LCD is x(x^2 - 4)
so multiplying through by this we get:-
2x(x + 2) + 7x = 5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x - 20 = 0
(3x + 4)(x - 5 ) = 0
so x = 5 , -4/3
Its the second choice

A.
Step-by-step explanation:
To find out the answer, there is a method that can be used to find out if a line is a function. It is called the vertical line method. And it also has to be per x, One y value has to be there. Analyzing the graphs, the answer should be option A.
