Which equation is represented by the graph below?

Firdavs [7]

let's proceed to graph each case to get the answer

using a graph tool

case a) $y=ln x$

see the attached figure N 1

The equation is not represented by the graph

case b) $y=ln x+1$

see the attached figure N 2

The equation is not represented by the graph

case c) $y=e^{x}$

see the attached figure N 3

The equation is represented by the graph ------> Is the solution

case d) $y=e^{x} +1$

see the attached figure N 4

The equation is not represented by the graph

therefore

the answer is

the equation is $y=e^{x}$
