Question

If E be a shifting operation applied to a function f, such that E(f) = f (x +β ), then?

(a) E (αf+β g) = α  E(f) +β  E (g)

(b) E (αf +β g ) =. ( α+ β ) + E (f + g)

(c) E (αf +β g ) = α E (f+gβ)

(d) E (αf +β g ) = αβ E (f + g)

I got this question in an interview for internship.

This question is from Syntax-Directed Definitions and Translations topic in section Syntax Directed Definition and Translations of Compiler

Answer 1

Correct option is (a) E (αf+β g) = α  E(f) +β  E (g)

Explanation: Shifting operation when performed gives this result.
