Answer:
b) in the vertex.
Step-by-step explanation:
In the vertex. If the parabola opens up or down the axis of symmetry is x = a where a is the x coordinate of the vertex.
If it opens to the left or right the axis is y = a where a is the y-coordinate if the vertex.
11. YES. Because each x-value is only used once (no duplicate x-coordinates)
12. range is the y-values. the lowest it goes is -2 (with an open dot), then it goes to +2 (with an open dot). then there is a separate line where y = 4.
Answer: (-2, 2) U [4, 4]
13. f(-1): when x = -1, y = ??? <em>(do not count the open dot!)</em>
Answer: 1
14. f(3): when x = 3, y = ??? <em>(do not count the open dot!)</em>
Answer: 4
Answer:
-4t
Step-by-step explanation:
9-t-3(t+3)
use distributive property and simplify
= 9-t-3t-9
= -4t
19 - 2 = 17 17 - 4 = 13 number = 13
