Answer:
The answer to your question is:
Step-by-step explanation:
Data
x² + 8x = -4y - 8
x² + 8x + 16 = -4y - 8 + 16
x² + 8x + 16 = -4y + 8
(x + 4)² = -4(y - 2)
(x + 4)² = 4(-1)(y - 2)
Vertex = (-4, 2)
p = 1
Focus = (-4, 1)
Axis of symmetry x = -4
Directrix y = 3
So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
Answer:
17.8
Step-by-step explanation:
9.5x = 3.25(52)
9.5x = 169
x = 169/9.5
x = 17.8
I don't know what is between f(x) and g(x), so (for now) there are two posible answers:
1.
- function multiplication:
2.
- function composition:
