How do i confirm that f and g are inverses?

see explanation

Step-by-step explanation:

To show f and g are inverses we require to show that

f(g(x)) = x and g(f(x)) = x

f(g(x))

= f(6x - 4)

= = = x

-----------------------------------------------------------------------------

g(f(x))

= g( )

= ( 6 × ) - 4

= x + 4 - 4 = x

-------------------------------------------------

Hence f and g are inverses

x-7*5

Step-by-step explanation:

The difference is subtraction and the question asks the difference of 7 and a number we can call that number x. So x minus 7 multiplied by 5, or in other words x minus 7 times 5.

Hope that helps, and good luck!
