Answer:
The domain is all real numbers
The range is all real numbers greater than or equal to [tex]-2[/tex]
Step-by-step explanation:
we know that
The function in the figure is a vertical parabola
The vertex of the function is the point [tex](0,-2)[/tex]
The parabola open upward------> the vertex is a minimum
The domain is the interval------> (-∞,∞)
The domain is all real numbers
The range is the interval------> [-2,∞)
[tex]y\geq-2[/tex]
The range is all real numbers greater than or equal to [tex]-2[/tex]
