Answer:
The domain is the interval (-∞,∞)
The range is the interval [-4,∞)
Step-by-step explanation:
we have
This is the equation of a vertical parabola in vertex form
The vertex is the point (-4,-4)
The parabola open upward (because the leading coefficient is positive)
The vertex represent a minimum
The domain is the interval (-∞,∞)
so
The domain is all real numbers
The range is the interval [-4,∞)
so
The range is all real numbers greater than or equal to -4
Answer:
x=6
Step-by-step explanation:
Given the x-intercepts of a parabola:
The equation of symmetry at the parabola's vertex is x=h
Where
In this case,
Therefore, the line of symmetry of the parabola is x=6 and is also the x-coordinate of the parabola's vertex.
