Answer:
The graph in the attached figure
Step-by-step explanation:
we have

This is the equation of a vertical parabola open up
The vertex is a minimum
Convert to vertex form
Complete squares

Factor the leading coefficient



Rewrite as perfect squares

The vertex is the point (-1.5,-1.5)
Find the zeros of the function
For y=0


square root both sides




Find the y-intercept
For x=0

The y-intercept is the point (0,3)
therefore
The graph in the attached figure
