The function is .

Function graph is

Let g(x) be the function of given graph.

Observe the two graphs f and g, the graph of g is a reflection in the x - axis followed by an upward shift of one unit of the graph .

So, the equation for g is .

The equation of graph is .

The function is .

Function graph is 

Let g(x) be the function of given graph.

Observe the points from two graphs f and g as follows:

The graph of g is horizontal shift of one unit to the right followed by an upward shift of one unit of the graph .

So, the equation for g is .

The equation of graph is .

The function is .

Function graph is

Let g(x) be the function of given graph.

Observe the points from two graphs f and g as follows:

The graph of g is a horizontal shift of three units to the left followed by a reflection in the x - axis followed by a downward shift of one unit of the graph .

So, the equation for g is .

The equation of graph is .
