Enter +1 for positive g (F increasing) or −1 for negative g (F decreasing), on each open interval. Infinity labels describe unbounded intervals

(-infinity, infinity)

What follows from this nonzero constant gradient?

Every primitive is a horizontal line

The primitive equals the constant gradient

Increasing linear primitives, with no stationary point

Every input is a stationary point
