Question

b) i) P = { 5, 10, 15, 20 } write in set builder form.
ii) Q = { x: x € W and 7 <x<15} write in roster form ​

Answer 1

Answer:

The relation mentioned in the figure shows, P a domain and Q as range.

Let the relation be R

In roster form R={(5,3),(6,4),(7,5)}

In set builder form R={(x,y):x∈P,y∈Q,y=x−2}

Step-by-step explanation:

A={x:x is an integer and−3<x<7}

The elements of this set are −2,−1,0,1,2,3,4,5, and 6 only.

Therefore, the given set can be written in roster form as

A={−2,−1,0,1,2,3,4,5,6}
