For a quadratic equation of this kind (a parabola), the range is determined by the maximum or minimum and comes in the form of
(,)
or
(,)
.
.
.
The min or max occurs at the vertex.
The only thing left to determine is whether f(3)=2 is a min or max value.
That's determined by the coefficient (a) of the term,
if a>0, parabola opens up, min value.
if a<0, parabola opens down, max value.
In this case, a=2, min. value.
.
.
.
The range of the parabola is then,
(,)
