Which expression is equivalent to (f + g)(4)?
f(4) + g(4), f(x) + g(4), f(4 + g(4)), 4(f(x) + g(x))

Solution:

The relation between a set of inputs containing one output is called a function.

It is denoted by f (x) where x is the input.

y = f(x) is the general representation

From the definition of function

We know that

(f + g) (x) = f(x) + g(x)

From the question

(f + g)(4) = f(4) + g(4)

Therefore, the expression equivalent to (f + g) (4) = f(4) + g(4).

Which expression is equivalent to (f + g)(4)?
f(4) + g(4), f(x) + g(4), f(4 + g(4)), 4(f(x) + g(x))

Summary:

The expression that is equivalent to (f + g)(4) is f(4) + g(4).
