The number of points of intersection of the two curves y = 2sinx and y = 5x 2 + 2x+3 is
Text Solution
Verified by ExpertsThe correct answer is:
A
Put y = 2sinx in
y = 5x 2 + 2x + 3 ⇒ ⇒ 2sinx = 5x 2 + 2x + 3
⇒ ⇒ 5x 2 + 2x + 3 – 2sinx = 0..... (i)
x = 
It is clear that number of intersection point is zero, because 0 ≤ ≤ sinx ≤ ≤ 1 and in all the values roots becomes imaginary.
