What is the domain of the graphed function?                                                                          

A)y ≥ 4

B)x ≥ -2

C)y ≥ -2

D)x ≤ -2

 

 

Use the graphs of f(x) = 2/x and g(x) = 1/-3-x to determine the solutions to f(x) = g(x).                                   

A)(-2, -1)

B)(-2, 1)

C)(2, 1)

D)(2, -1)

"Domain" refers to the x values covered by the graph....

 

The least x value  is at x  = -2 and from here, all x values > -2  are covered

 

So....the domain is  x ≥ -2

 

 

The solution to  f(x)  = g(x) is the point where the graphs  intersect.....this is at  ( -2, - 1 )
