If f(x)=2x/7+4, which of the following of the inverse of f(x)?

a. f-1(x)= 2(x-4)/7
b. f-1(x)= 7(x+4)/2
c. f-1(x)= 2(x+4)7
d. f-1(x)= 7(x-4)/2

explain how you got the answer

Option D is correct.

Step-by-step explanation:

Given : function f(x) =

We have to find inverse function of f(x)

Le, y be any arbitrary image of f(x).

So,   y = f(x)

So, Inverse of f(x) is

Therefore, Option D is correct.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
