Which Expression is Equivalent to (f + g)(4)?
a) f(4) + g(4) b) f(x) + g(4) c) f(4 + g(4)) d) 4(f(x) + g(x))

Solution:

We will be using the concept of functions to solve this.

Given that, (f + g)(4)

We know from the definition of function that (f + g) (x) = f(x) + g(x)

⇒(f + g) (4) = f(4) + g(4)

Thus, the expression (f + g)(4) is equal to f(4) + g(4).

Which Expression is Equivalent to (f + g)(4)? a) f(4) + g(4) b) f(x) + g(4) c) f(4 + g(4)) d) 4(f(x) + g(x))

Summary:

The expression (f + g)(4) is equal to f(4) + g(4).
