Problem 3 [4pt] Define a function f in Racket such that it takes in 3 arguments a, b, c and returns a function g such that g(1) = ax+bx+c The code below gives you a definition of f that takes in 3 arguments a, b, c and returns a function g such that g(x) = 0 for all c. Modify the 0 in the definition code so that your program gives the right answer 4, 9, 18 respectively for the 3 expressions following the definition. #lang racket (define (f a b c) (lambda (x) 0)) ((f 2 3 4) 0) ( (f 2 3 4) 1) ((f 2 3 4) 2)
