AleksandrR [38]

Answer:

The correct answer to the following question will be "60 students".

Step-by-step explanation:

Marta will be taking a sampling frame from some kind of 600 student group.

Mean,

N = 60  

Although the sampling method could perhaps consist of the following components 10% of the population,

What is the inverse of the function f(x) = x + 2?
nadya68 [22]

Answer: h(x)=x-2

Step-by-step explanation:

To find the inverse of the function f(x) = x + 2, the first  step is to replace f(x) with "y":

 f(x) =y= x + 2\\\\ y = x + 2

The second step is to solve for the variable "x":

x=y-2

The third step is to interchange the variables, then:

y=x-2

Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:

h(x)=x-2
