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:
The value of the test statistic
Step-by-step explanation:
From the question we are told that
The high dropout rate is %
The sample size is
The number of dropouts
The probability of having a dropout in 1000 people
Now setting up Test Hypothesis
Null
Alternative
The Test statistics is mathematically represented as
substituting values
17. (x^2-x+3)(4x+1)
18.(x+2)(x) - (7)(3)
Where’s the table if I could see it I could help
