The rule for reflecting a point over the y-axis is this:
(x, y) ---> (-x, y)
The x term becomes the opposite and the y term stays the same
(3, 4) ---> (-3, 4)
Hope this helped! Let me know if you have any further questions!

Answer:
Step-by-step explanation:
The temp is 100 at time t = 0
After 1 sec, the temp difference would be:
After 2 sec, the temp difference would be:
Similarly for 3 seconds, 4 seconds etc.
We notice that the parenthesis part is 40% of it, so we can also write:
100(40%)^t,
where
t is the time
40% can be written as 40/100 = 0.4
SO, the function is:
Answer:
8. -(70a^2b^2c)
10. 12xy(3y-4x)
11. (t-12)(t-4)
