For a recent year, the rate of first-class postage is as follows:
Law Incorporation [45]

Answer:

$0.95

Step-by-step explanation:

Given that weight of the function = x

Given that cost of the postage for mail having weight less than or equal to 1 oz = $0.44

then to find the equation can be written as

C(x)=0.44  where 0<x<=1

Similarly we can write equation for other parts

C(x)=0.61  where 1<x<=2

C(x)=0.78  where 2<x<=3

C(x)=0.95  where 3<x<=3.5

Now we can write them together as piecewise function as shown in below:

C(x)=\left\{\begin{matrix}0.44 & 0

to graph that we just draw horizontal lines for each as none equation contains x on the right side .

3.48 oz is less that 3.5 so we will use $0.95.
