N/5 + 9 = 22
5(n/5 + 9 = 22)
n + 45 = 110
n = 65
Ok so you are correct that x is input and y is output
the
you could be talking about a function in general or a kind of function normally used called a one-to-one function which I will assume you are talikning about
one-to-one funciton has that for every input, there is only 1 output, ie, x never repeats with a diffent y
example
(1,2), (2,2) is a function since x didn't repeat
(1,2), (1,3) is not since x repeats with a different y
points given are
(-5,1),(-3,-2), (3,0),(1,1),(2,0),(6,4)(8,-2),(8,7)
we see that the points (8,-2) and (8,7) make it not a function since it is the same input (8) that gives 2 different outputs
professor octavious is wrong since 8 repeats
Volume = area of cross-section x length
= 7 1/3 x 2
= 22/3 x 2/1
= 44/3
= 14 2/3
= 14.666666667
V = 44/3 (or 14 2/3, double of 7 1/3)
Hope this helps!
