Assume it costs 30 cents to mail a letter weighing one ounce or less, and then 28 cents for each additional ounce or fraction of an ounce. Write a piecewise-defined function P(x) that represents the cost, in cents, of mailing a letter weighing between 0 and 3 ounces.

Step-by-step explanation:

We are given the following in the question:

Cost of sending a mail  =

30 cents for 1 ounce or less.

28 cents for each additional ounce or fraction of an ounce.

Let x represent the weight of mail. Let P(x)  represents the cost in cents.

Weight of mail between 0 and 1 ounces

Weight of mail between 1 and 2 ounces

Weight of mail between 2 and 3 ounces

Thus, we can write the piecewise function for cost in the following manner:

where x is in ounces and P(x) is the cost in cents.

can someone answer this question plz

step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
