this problem the universal set will be R. Define the following sets using interval notation: A = [5, 8] B = [6, 9) C = (0, 6) D = [8, ∞)   Find each of the following relative complements: B − A, D − C, A − D

Let ai = [250] -10 and a2 = h [4] The set {a1, a2} will span R² unless h = (If there are no values of h that make the set fail to span, enter "NONE". If the set fails to span for all values of h enter "ALL".)

Write each of the following sets in correct roster notation:(a) {x^2 - 1 : x∈{0,1,2,3,4}}(b) {x∈{0,1,2,4} : x 2 ≥ 5}

Suppose A and B are two finite sets such that |B| = |A| - 1 and the number of relations on A is 512. Determine: |B|:  Number of relations from B to A:
