Exercise: Matching Examples and Function Definitions

Directions: Match the EXAMPLEs on the left with the definitions on the right. NOTE: Some definitions may not match any examples!

(EXAMPLE (mystery "red") (circle 10 "solid" "red")) (EXAMPLE (mystery "orange") (circle 10 "solid" "orange"))
f
(define (mystery c) (circle 10 "solid" c))
(EXAMPLE (mystery 30) (circle 30 "outline" "red")) (EXAMPLE (mystery 10) (circle 10 "outline" "red"))
a
(define (mystery r) (circle r "outline" "red"))
(EXAMPLE (mystery 30) (rectangle 30 10 "outline" "red")) (EXAMPLE (mystery 10) (rectangle 10 10 "outline" "red"))
c
(define (mystery w) (rectangle w 10 "outline" "red"))
(EXAMPLE (mystery 30) (rectangle 20 30 "solid" "red")) (EXAMPLE (mystery 20) (rectangle 20 20 "solid" "red")) (EXAMPLE (mystery 10) (rectangle 20 10 "solid" "red"))
g
(define (mystery h) (rectangle 20 h "solid" "red"))
(EXAMPLE (mystery 2) (+ 2 2)) (EXAMPLE (mystery 4) (+ 4 4)) (EXAMPLE (mystery 5) (+ 5 5))
d
(define (mystery num) (+ num num))
