Hi!
We can see here that this is a composition question.
And since the composition of g of f of x is x, we can conclude that g(x) is the inverse of f(x) (if you're confused, search up the definition of an inverse function).
To find an inverse function, we can take the f(x) function and change the positions of the x and y variables.







Which is answer choice A, to check your work, you can solve the composition of g(f(x)), which will get you x.

Answer:
Addition Property of Equality
Step-by-step explanation:
You are adding 3/4 to both sides to isolate the <em>x</em>.
Answer:
5x^4 -7x^3-5x^2+5x+1
Step-by-step explanation:
Hey!
You would just add all the numbers up, and by making sure that you combine all like terms. In this case it is just 1-0 = 1 and so the solution would be the same as your question but with a 1 and you would get rid of the -0.
Hope this helps!
