Answer:
D: [8 , 12]
R: [-10 , -6]
Step-by-step explanation:
Well for this parabola domain and rage are acttually limited because of the solid dots you see on the graph.
So first things first, what is range? Well range is the amount of y values on a line or anything in a graph.
And what’s domain? Domain is the amount of x values on a line or whatnot.
So let’s do domain first.
On the parabola the first x value is 8 and the last is 12 so we have to write this in interval notation which is [8 , 12].
Now for range the lowest y value is -10 and the highest is -6 so in interval notation it is [-10 , -6].
