For the function g(x)=14/x+3, find (g^-1o g)(4)

by definition, (g^-1 o g)(x) = x,

so, 4.

thank you but how do you solve

To find the composition (g^-1o g)(4) for the function g(x) = 14/x + 3, we need to follow these steps:

1. Find the inverse of g(x), denoted as g^-1(x). The inverse function reverses the input and output of the original function.

To find the inverse of g(x), swap the position of x and y in the equation g(x) = 14/x + 3:

x = 14/y + 3

Then, solve for y:

y = (x - 3)/14

Therefore, the inverse function is g^-1(x) = (x - 3)/14.

2. Substitute 4 into g(x).

Replace x in g(x) = 14/x + 3 with 4:

g(4) = 14/4 + 3

Simplifying further:

g(4) = 3.5 + 3

g(4) = 6.5

3. Apply the inverse function g^-1 to the result obtained in step 2.

To find (g^-1o g)(4), we substitute the value 6.5 into the inverse function g^-1(x):

g^-1(6.5) = (6.5 - 3)/14

Simplifying further:

g^-1(6.5) = 3.5/14

g^-1(6.5) = 0.25

Therefore, (g^-1o g)(4) = 0.25.
