Question 953257: given:y = -x-3 ; sketch the graph and determine the inverse algebrically verify your solution graphically
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
given:y = -x-3 ; sketch the graph
Plot (0,-3) and (-3,0)
Draw a line thru them::

------------------------------------
and determine the inverse algebrically
Ist: Interchange x and y::
x = -y-3
2nd: Solve for "y":
y = -x-3
--------------
verify your solution graphically
The function is its own inverse.
