Answer:
No, it is not a function because one of the x values have two different y values
Multiply length times width to find the area. 6.5x11= 71.5
It is undefined because you can’t have 0 as a denominater
9 = c(c - 8)
9 = c² - 8c
c² - 8c - 9 = 0
c² + c - 9c - 9 = 0
c(c + 1) -9 (c + 1) = 0
(c+1)(c-9) = 0
c = -1 or 9
In short, Your Answers would be -1 and 9
Hope this helps!
