평소에 축구를 좋아하던 성훈이가 축구에서 기대 득점 값에 일정한 규칙이 있다는 것을 알아냈다.
축구 경기장이 이러한 모양일때 축구 선수가 슈팅을 때린 위치를 O로 잡고 선분 AB의 중점을 M으로 놓는다.
이때 선분 CD와 점O의 거리를 x로 두고 각 OMA과 각 OMB 중에서 각도가 90도 이하인 각의 각도를 y라고 둔다.
이때 기대득점은 f(x)와 g(y)의 합이다.
x의 값이 75이고 y의 값이 50일때 기대득점은 0.59
x의 값이 90이고 y의 값이 50일때 기대득점은 0.71
x의 값이 95이고 y의 값이 50일때 기대득점은 0.8375
x의 값이 85이고 y의 값이 45일때 기대득점은 0.681이다
이 때 이차함수 f(x)와 이차함수 g(x)의 규칙을 각각 찾으시오.
