Find n(4) for the function, n(u) = 4.

N(4) = 4

Step-by-step explanation:

The given function is N(u) = 4, where N is the function and u is the independent variable.

Now, the value of the function N(u) is a constant and independent of u variable.

Therefore, for each and every value of the variable u the N(u) will be 4 and this is a constant function.

Hence, N(4) = 4 ( Answer )
