Answer 1

Answer : 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
