Question

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

Answer 1

(m º n)(x) = x -2

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
