Which of the following are accepted without proof in a logical system? check all that apply.

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
