Question

X+ 5
If m(x)= x+1 and n(x) = x - 3, which function has the same domain as (mºn)(x)?

Answer 1

Answer:

(m º n)(x)  =  x -2

Step-by-step explanation:

Here, in the given expression:

m(x)= x+1   and    n(x) = x - 3

To find :  (m º n)(x)

Now, solving for  (m º n)(x)

  (m º n)(x)  = m (n (x))  = m (x-3)

also,  m (x-3)  = (x -3) + 1  =  x -2

So, (m º n)(x)  =  x -2
