Question 366636: For the quadratic function f(x)= -x^2+2x+3, give the coordinates(ordered pair)of the x-intercept(s), y-intercept(s), and the vertex of the parabola. If the parabola has a maximum or minimum, give its coordinates.

For the quadratic function:
\ =\ ax^2\ +\ bx +\ c)
The 
-intercepts are:
)
and
)
The 
-intercept is:
))
The vertex of the parabola is:
\right))
If 
, then the parabola opens upward and the vertex is a minimum. If 
, then the parabola opens downward and the vertex is a maximum.
