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
Your adding 5 every time :)
Answer:
The third one
Step-by-step explanation:
It can't be the first one since the peak is 4 since it is the highest
It can't be the second one because the data is all different
It could be the third one since their are gaps
And It can't be the fourth one because the range is 7
So it must be the third one
