Which equation is represented by the graph below?

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

using a graph tool

case a)

see the attached figure N 1

The equation is not represented by the graph

case b)

see the attached figure N 2

The equation is not represented by the graph

case c)

see the attached figure N 3

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

case d)

see the attached figure N 4

The equation is not represented by the graph

therefore

the answer is

the equation is

Equation  represents the graph shown in given figure.

Hence option (3) is the correct option.

The function given in the options of the figure are

The graphs of all the options are attached below

The options (1) and (2) are logarithmic function and options (3) and (4) are exponential function

The addition of constant shifts the function upwards  or downwards depending upon the sign of constant.

hence for

The function is shifted by 1 unit in +y direction.

Similarly we can conclude about the logarithmic function.

The graph shown in figure is similar to the function hence option (3) is correct.

It can be seen that for   the y values are always positive and x values vary from .

So option (3) is the correct option.

Equation  represents the graph shown in given figure.
