what must be the equation to get this type of a curve??
the curve must increase from -infinity to 0 and then decrease again to +infinity.
Thank you

You can try multiplying a $\sin$ wave with a Gaussian, e.g:
$$\sin(5x)e^{-x^2/2}$$

y=sin(x)/x has this property.
sin(x)/x function has a special name: sinc(x)
It is an important function. For example it is the Fourier transform of the rectangular pulse which plays a major role in signals and systems analysis.
