the parabola is upward or downward depending on the position=
a) So this one is upward
and the vertex is the minimum value of y, (in upward parabola)
so the vertex here, we can see from the graph is: x=2 and y=2
b) (2,2)
the axis of symmetry is the x value of the vertex, so:
c) x=2
the parabola never crosses the x-axis, so
d) x-intercept= none
and the y-intercept is when the line cross over the y axis, so:
y-intercept= 6
