The graph shown in figure is exponential. Write down the equation corresponding to the graph.

• A

  $y=-4+10\left(1-e^{-Kx}\right)\text{. Here, }K\text{ is positive constant }$

• B

  $y=-4-10\left(1-e^{-Kx}\right)\text{. Here, }K\text{ is positive constant }$

• C

  $y=-4+10\left(1-e^{Kx}\right)\text{. Here, }K\text{ is positive constant }$

• D

  $y=4+10\left(1-e^{Kx}\right)\text{. Here, }K\text{ is positive constant }$
