אשכול מראות פרבוליות - מוקד, מדריך ומה שביניהם - חלק ב - הקדמה

1.1 מדרגה 1 לבעיית מטרה 1

בעיה 1.1.1

בסרטוט הבא נתון כי:

הפונקציה $h(x)$ היא פרבולה.

הנקודה $F(0,2)$ היא מוקד הפרבולה. הישר m הוא מדריך הפרבולה.

הנקודה C נמצאת על הפרבולה. שיעור ה- y של נקודה C הוא 4.5.

הישר CR מקביל לציר ה- x.

מצאו את:

הביטוי האלגברי למדריך הפרבולה.
אורך הקטע FC.
שטח משולש FCR.

אחרי שפתרתם את השאלות במדרגה 1, חזרו לבעיית מטרה 1.
או, במידת הצורך, פתרו את השאלות במדרגה 2.
