Question

1)Let f: A → B be a function
defined by f(x) = x/2-1,
where
A = {2,4,6,10,12} and B =
{0,1,2,4,5,9}. Represent f by
(i) set of ordered pairs (ii) a
table (iii) an arrow diagram (iv)
a graph​

Answer 1

Answer:

A={0,1,2,3},B={1,3,5,7,9}

f(0)=2(0)+1=0+1=1

f(1)=2(1)+1=2+1=3

f(2)=2(2)+1=4+1=5

f(3)=2(3)+1=6+1=7

(i) A set of ordered pairs

f={(0,1),(1,3),(2,5),(3,7)}
