Answer : { x| x>1 }
The graph of the function is [tex]y=(x-1)^2 -4[/tex]
The equation is in the form of [tex]y=a(x-h)^2 + k[/tex]
where (h,k) is the vertex
from the given function [tex]y=(x-1)^2 -4[/tex]
the vertex is (1,-4)
The graph is decreasing till x=1
then the graph starts increasing after x=1
So the x values for which the function is increasing is x>1
