Unformatted text preview: ) . Suppose that f is diﬀerentiable on ( a,c ) and ( c,b ) . (a) Prove the following test for determining whether c is a relative minimum: If there is a neighborhood ( cδ,c + δ ) ⊆ [ a,b ] such that ● for all x ∈ ( cδ,c ) , f ′ ( x ) ≤ 0, ● and, for all x ∈ ( c,c + δ ) , f ′ ( x ) ≥ 0, then f has a relative minimum at c . (b) Write down the analogue for a relative maximum....
