The diagram shows a function. State the value b.

The diagram shows the relation between set P and set Q. State the type of relation.

The following diagram shows the function  $f\left(x\right)$   =  $3x$   for the domain  $1\le x\le5.$  Determine the value of  $a$   and  $b$  .

• a = 9 , b = 15

• a = 15, b = 9

• a = 8 , b = 14 

• a = 7, b = 12
