we have

Step

Find the value of

calculate the value of f(x) for

Step

Find the value of

calculate the value of g(x) for

so

therefore

the answer is

Value of g (f (2)) = 3

Set A to set B is said to be a function if each member of set A pairs is exactly one member of set B

So, one value of x is only assigned to one value of y

A function can be expressed in the form of a cartesian diagram, sequential pairs, or arrow diagram

Like the number operations we do in real numbers, operations such as addition, subtraction, division or multiplication can also be done on two functions.

Suppose a function f (x) and g (x) then:

(f + g) (x) = f (x) + g (x)

(f + g) (x) is a new function of the sum of f (x) and g (x)

the other function operations:

In addition to the above operations, we can combine two functions using the function composition with the symbol "o"

(fog) (x) = f (g (x))

(gof) (x) = g (f (x))

Given

Then g(f (2))

f(2) = 4.2 -3

f(2) = 5

g(f (x) = g (5)

g(5) = 3

so g(f(2)) = 3

F (x) = x2 + 1, g (x) = 5 - x
