Match roster forms with the set builder form.
(i) {p,r,I,n,c,a,l} (a) {x : x is a positive integer and is a divisor of 18}
(ii) {0} (b) {x : x is an integer and `x^(2)-9=0}`
(iii) {1,2,3,6,9,18} (c) {x : x is an integer and x+1=1}
(iv) {3,-3} (d) {x : x is a letter of the word PRINCIPAL}

Match each of the set on the left described in the roster form with the same set on the right described in the set-builder form : (i) {P, R, I, N, C, A, L} (a) { x : x is a positive integer and is a divisor of 18} (ii) { 0 } (b) { x : x is an integer and x^(2) – 9 = 0 } (iii) {1, 2, 3, 6, 9, 18} (c) {x : x is an integer and x + 1= 1 } (iv) {3, –3} (d) {x : x is a letter of the word PRINCIPAL}

Match the roster form with set builder form. (i) {1,2,3,6} (a) {x : x is prime number and a divisior of 6} (ii) {2,3} (b) {x : x is an odd natural number smaller than 10} (iii) {m,a,t,h,e,m,a,t,i,c,s} (c) {x : x is a natural number and divisor of 6} (iv) {1,3,5,7,9} (d) {x : x is a letter of the word MATHEMATICS}
