vfiekz [6]

Answer:

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$

Step-by-step explanation:

Given: $h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

To find: $h^{-1}(x)$

Solution:

Inverse of a function exist if it is both one to one and onto.

$h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$

gogolik [260]

Answer:

$150

Step-by-step explanation:

Given

Delivery amount = $120

Percent tip on the delivery amount = 15%

Tip amount = 15% * 120

Tip amount = 0.15 * 120 = $30

Total money paid = Delivery amount + Tip

Total money paid = $120 + $30

Total money paid = $150

hence the total money you will give the delivery boy is $150
