Answer:
4.5 sq. units.
Step-by-step explanation:
The given curve is
⇒ ...... (1)
This curve passes through (0,0) point.
Now, the straight line is y = 3x - 6 ....... (2)
Now, solving (1) and (2) we get,
⇒ (y - 3)(y + 2) = 0
⇒ y = 3 or y = -2
We will consider y = 3.
Now, y = 3x - 6 has zero at x = 2.
Therefor, the required are =
=
=
= 6 - 1.5
= 4.5 sq. units. (Answer)
