Answer:
f(n)=o.15n. is you answer
The domain is all the integers from 0 to 30, inclusive.
The domain is the set of all the possible inputs (x-values), this is 0 paintings, 1 painting, 2 paintings, ... until 30 paintings.
I believe it is D but it may be B
If we see the protractor, we ill see that there is a horizontal line and a slant line. We have to see where the slant line touches the protractor. And as we see that the slant line touches the protractor at two angles which are 150 degree and 30 degree. But since the angle is acute , so 150 degree is not possible . So the correct option is 30 degree.
-X²-4+7
=-X²+3
a=-1 b=0
X=-b/2a
X=0
If X=0, Y=3
So the Vertex is (0, 3).
That's your answer.
