It's unclear what the planes are supposed to be, so I'll take and
with
.
The cross sections are disks with diameter , so each disk of thickness
has a volume of
Then taking infinitesimally thin disks, we find the solid has a volume of
Since
and
it follows that the volume is
Answer:
x<-2
Step-by-step explanation:
Answer:
See attached picture.
Step-by-step explanation:
Graph the function as (x,y) points.
(-3,5)
(4,6)
(6,-9)
(9,-10)
These are graphed in black on the picture.
To graph the inverse, switch the points from (x,y) to (y,x).
(5,-3)
(6,4)
(-9,6)
(-10,9)
These are graphed in red on the picture.
