If f is a real valued function such that

f\left( {x + y} \right) = f\left( x \right) + f\left( y \right)\;and\;f\left( 1 \right) = 5

, then the value of

f\left( {100} \right)

View answer and explanation

Correct option: D

500

Option D (500) is correct because the function is linear, and

f(100) = 100 * f(1) = 500
