Vertex is

Axis of Symmetry is

The curve is opening upwards.

#### Explanation:

#y=(x-2)^2-1#

It is a quadratic equation.

It is in the vertex form.

#y=a(x-h)^2+k#

Th vertex of the given function is -

#h=-1(-2)=2#

#k=-1#

Vertex is#(2,-1)#

Axis of Symmetry is

Its

Hence the curve is opening upwards.
