Question

Let f:A ➡B be a function defined by f(x) =x/2-1 where A={2, 4,6,10,12}, 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

Step-by-step explanation:

f(x)= x/2-1

A={2,4,6,10,12}. (substitute A in f(x))

f(2)=2/2-1=2-2/2=0

f(4)=4/2-1=4-2/2=1

f(6)=6/2-1=6-2/2=2

f(10)=10/2-1=10-2/2=4

f(12)=12/2-1=12-2/2=5

Set of ordered pair:

-----------------------------

(a,b)

f={(2,0),(4,1),(6,2),(10,4),(12,5)}
