Let f RR be a differentiable function and f(0) = 1. Prove by contrapositive statement: If f'(x) ≤ 2 for x ≤ (0,3), then ƒ(3) ≤ 7. Let A and B be n x n real matrices. (a) Prove by contradiction: if B 0 and AB = 0, then A is singular. (b) Write down the contrapositive statement and prove: if B ‡ 0 and AB = 0, then A is singular.
