1. <u>Too broad:</u> what will the economy be like in the future?
2. <u>Effective:</u> how can virtual reality (VR) be used in health care?
3. <u>Too narrow:</u> how many gallons of water will we use in 2025?
4. <u>Effective:</u> what are the best strategies for <u>increasing</u> food production in the future?
A research question can be defined as a specific inquiry (question) that a research work seeks to provide an answer or response to, especially by using scientific methods such as the following:
- Documenting critical information.
According to their nature, a research question is broadly classified as follows:
1. <u>Too broad:</u> what will the economy be like in the future?
- A country's economy has many facets and as such it would be difficult to write about what it would be like in the future in one research paper.
2. <u>Effective:</u> how can virtual reality (VR) be used in health care?
- Virtual reality (VR) is a modern technology that is effectively used by medical professionals in the field of medicine to provide health care for various patients.
3. <u>Too narrow:</u> how many gallons of water will we use in 2025?
- The quantity of water in gallons that would be used in 2025 can easily be calculated by using a simple formula and as such the answer to this question can be provided in a sentence.
4. <u>Effective:</u> what are the best strategies for <u>increasing</u> food production in the future?
- The best strategies to be adopted for an increase in food production in the future can be developed into a full research paper based on strategies that have been used in the past.

Recall that √x has a domain of x ≥ 0.
So, f(x) is defined as long as
(x + 1)/(x - 1) ≥ 0
• We have equality when x = -1
• Otherwise (x + 1)/(x - 1) is positive if both x + 1 and x - 1 are positive, or both are negative:
Then the domain of f(x) is
x > 1 or x ≤ -1
On the other hand, g(x) is defined by two individual square root expressions with respective domains of
• x + 1 ≥ 0 ⇒ x ≥ -1
• x - 1 ≥ 0 ⇒ x ≥ 1
but note that g(1) is undefined, so we omit it from the second domain.
Then g(x) is defined so long as both x ≥ -1 *and* x > 1 are satisfied, which means its domain is
x > 1
f(x) and g(x) have different domains, so they are not the same function.
Heat and light energy gets transformed as energy for the plants to grow via the process of photosynthesis. The cows eat the grass, using the grass as an energy source to live and move around. Thus the grass, though indirectly, provides a means of kinetic energy that the cows use to move around and graze in the meadow.
