y=-2(x-1)^3 domain, range, relative minimum or maximum and what it's increasing and decreasing on
Thank you for the opportunity to help you with your question!
The domain and range of ANY
cubic is all real numbers since any "x" value can be plugged into the
cubic (there is no division by zero or square roots to worry about).
Domain: all real numbers which in interval notation is ( ,)
Range: all real numbers which in interval notation is ( ,)
increasing on an
interval if, for any x1 and x2 in
interval, x1 < x2
implies f(x1) < f(x2),
