Which expression is equivalent to (f + g)(4)? a; f(4) + g(4) b; f(x) + g(4) c; f(4 + g(4)) 4 c; (f(x) + g(x))

Keywords:

Function, sum of functions, properties of functions, real numbers

For this case we have a sum of functions that we must represent in an equivalent way. For this we take into account that by definition, the sum of functions property establishes that:

The function is defined in the set B, (Being B belonging to the real numbers) as:

for all x belonging to set B.

Then, according to the given definition we have:

Thus, the expression is equivalent to
