Let A(4, -4) and B(9, 6) be points on the parabola y² = 4x. Let C be a point chosen on the arc AOB of the parabola, where O is the origin, such that the area of ΔACB is maximum. Then, the area (in sq. units) of ΔACB is:
3012
3134
32
3114
Solution:
Area=5|t²-t|=5|(t-½)²-¼| Area is maximum when t=½ therefore Area=3114
