Easy - math - inverses - need asap and you very much!

check my answers for two problems and do one for me - and you! just reassure me that they are right and if im wrong tell me what i did!

Part 1) No

Part 2) Option 4.

part 3)

Step-by-step explanation:

Part 1) we have

Find the inverse of f(x) and then compare with g(x)

Let

y=f(x)

Exchange the variables x for y and y for x

Isolate the variable y

Let

therefore

the functions f(x) and g(x) are not inverses of each other

Part 2) we have

Let

y=f(x)

Exchange the variables x for y and y for x

Isolate the variable y

Let

Part 3) we know that

For ,

so

For ,

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
