finding the domain of a real-world piecewise function
lucy needs to buy some organic apples, and her grocery store is having a sale on them. if she buys 3 or fewer
pounds of apples, the price will be $1.50 per pound. if she buys more than 3 pounds of apples, the price is $1.10 per
pound. what is the domain of the piecewise-defined function, where x represents the number of pounds of apples?

intro

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

is the anwser b. (-13)?

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
