The number of ordered pairs

\left( {x,y} \right)

satisfying

y = 2\sin \,\,x\;\,\mathrm{and}\,\;y = 5{x^2} + 2x + 3

View answer and explanation

Correct option: A

Option A (0) is correct because the two equations

y = 2\sin x

and

y = 5x^2 + 2x + 3

have no intersection points, hence no solutions.
