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).
