Question
f(x) = | 2x -3 | - 1 ; g(x) = | x2 -2x | ; at how many points these two
graphs will intersect in the first quadrant?
graphs will intersect in the first quadrant?
Answer: Option A
:
A
Graphs will intersect at only one point in the first quadrant
In the first quadrant, both f(x) and g(x) will be positive.
2x- 3 - 1 = x2 - 2x
x2 - 4x + 4 = 0
∴ (x- 2)2 = 0
x=2 at only one point.
