Answer 1

Answer : { x| x>1 }

The graph of the function is $y=(x-1)^2 -4$

The equation is in the form of $y=a(x-h)^2 + k$

where (h,k) is the vertex

from the given function  $y=(x-1)^2 -4$

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
