Answer:
D. The last option
Explanation:
You can't divide by 0, so find out when the given function is discontinuous.

You can see that x is discontinuous at x=-1,1, so find a piecewise function that fill in those gaps.
Plug x=-1,1 into your function to find out what values you need to fill in. But of course it's discontinuous at those points, so plug in a number near x=1 and x=-1. I chose x=-1.1 and x=1.1


so we need to fill in 2 at x=-1, and fill in 4 at x=1

Case Studies:
Studying or recording one subject, and/or the subject's life and developments over long periods of time (sometimes over the course of their whole lives)
Surveys:
A study tool to collect data amongst several individuals in a population. May be used to find out factual information, or simply one's opinion on a certain topic.
Naturalistic Observation:
Observing subjects in their natural environments! (Like observing a child's behaviors at home, where they feel most comfortable. When observing in places where they may not be comfortable, behavior of the subject is due to change.)
Answer:
Crops are now immune to many diseases and insects.
Explanation:
The constant advancement of science and technology within agriculture has been very beneficial to the better use of crops and to stimulate a better food supply, which has a beneficial impact not only on the lives of consumers, but also on the economy. One of the greatest benefits presented by this advance in science and technology is the ability to give agricultural crops resistance to pests and diseases. This is possible thanks to genetic engineering and advances in the study of agricultural entomology and microbiology, which have allowed scientists to manipulate plants to resist attack by harmful insects and microorganisms in agriculture. This resistance allows the plants to develop well and to produce products suitable for sale.
