Question

Help! I do t understand

Answer 1

The correct answer is second option 2

(f o g)(x) = 2

Explanation:

It is given that,

f(x) = x and g(x) = 2

To find (f o g) (x)

We have f(x) = x and g(x) = 2

we can write (f o g)(x) as

(f o g)(x) = f(g(x))

g(x) = 2

f(g(x) = f(2)

f(x) = x

f(2) =2

Therefore the correct answer is second option 2

Answer 2

Hello!

The answer is: The correct option is the second option, 2.

Why?

We are working with composite functions. Composite functions mean to evaluate a function in another function.

Composite function:

`(f\circ g)(x)=f(g(x))`

So, for this case, where there is a variable "x" we need to rewrite it with the function g(x)

Then,

`(f\circ g)(x)=(g(x))=(2)\\(f\circ g)(x)=2`

Hence, the correct option is the second option, 2.

Have a nice day!
