[잡담] 제 썸네일 만들기

눈 모양 함수 1

y = -\frac{1}{100}(x + 100)^{2} + 70   (단, -150 \leq x \leq -50 ),

눈 모양 함수 2

y = -\frac{1}{100}(x - 100)^{2} + 70  (단, 50 \leq x \leq 150 ),

입 모양 함수

y = \frac{1}{150}x^{2} - 70  (단, -100 \leq x \leq 100)

입니다!

 

참고로 저는 제 썸네일처럼 정교하게 못그리고

제 컴퓨터 프로그램님(?)께서 그려주셨어요ㅎㅎ

 

(이차함수를 알아야 썸네일을 그릴 수 있다는 게 함정)
