f(g(x)) You plug in g(x) for x
f(x) = 2x + 3
f(g(x)) = 2(g(x)) + 3
f(g(x)) = 2(4x - 5) + 3
f(g(x)) = 8x - 10 + 3
f(g(x)) = 8x - 7
g(f(x)) You plug in f(x) for x
g(x) = 4x - 5
g(f(x)) = 4(f(x)) - 5
g(f(x)) = 4(2x + 3) - 5
g(f(x)) = 8x + 12 - 5
g(f(x)) = 8x + 7
Answer: 84.13%
Step-by-step explanation:
Given : The scores in a a language test with normally distributed.
Mean : 
Standard deviation: 
Let x be the random variable that represents the scores of students.
Formula for z-score: 
For x= 60 , we have

The probability f test takers scored a 60 or above :-

Hence, the percentage of test takers scored a 60 or above = 84.13%
Answer: hello your question is incomplete attached below is the complete question
Answer : g(x), j(x), k(x), f(x), m(x), h(x)
Step-by-step explanation:
The Arrangement of the functions in ascending order ( i.e. starting from the least to the Highest ) is based on the definition of the denominator for all the real values of x and the continuation of the function on the set of real numbers.
when resolving the given functions input the value of x = 5 into the given function to determine the above conditions
g(x) ; has its denominator defined for all real values of x , hence the function g(x) is continuous on the set of real numbers
