Given the functions f(x)=1/x−3+1 and g(x)=1/x+4+3 .

Which statement describes the transformation of the graph of function f onto the graph of function g?

The graph shifts 2 units right and 7 units down.

The graph shifts 2 units left and 7 units up.

The graph shifts 7 units right and 2 units down.

The graph shifts 7 units left and 2 units up.

 

2.

What are the coordinates of the hole in the graph of the function f(x)?

 

f(x)=x2+3x−28/x+7

1. The graph shifts 7 units left and 2 units up.

 

2. f(x)  =  x^2 + 3x - 28             (x + 7) ( x - 4)             x  -  4

              ___________    =      ____________  =  

                 X + 7                          x +  7

 

The " hole"  occurs at   x  =  -7   and  y  = (-7) - 4  =  -11

So ⇒   (-7, -11)
