My work is in the paint doc... my only question is... why is the radi 1x and not 1+x?
My reason for why I think it is 1  x is in the paint doc, please let me know why I am wrong.. thank you.

Calculating volume.. easy question
Much better  thanks!
The horizontal distance from a point (x, y) on your exponential curve to the line x = 1 is 1  x. For most of the interval [1, 0], the x values are negative, so this distance will generally be larger than 1, but less than 2. Also, the point is labelled incorrectly. It should be (x, f(x)), not (x, f(x)).

it should be (x,f(x)) even though its in the 2nd quad? is this general for all quad that x and f(x) be positive when labeling an arbitrary coordinate ?

Think about the xaxis. If x is a number to the left of zero, it's negative. We DO NOT write this as x.
