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.

The theory of plate tectonics cannot be used in explaining: the origin of the Earth's core.
<h3>What is a tectonic plate?</h3>
A tectonic plate is also known as lithospheric plate and it can be defined as an enormous, solid, irregularly shaped rock slab, that comprises two (2) plates:
- Continental plates
- Oceanic plates
<h3>The theory of plate tectonics.</h3>
The theory of plate tectonics states that the solid outer crust of planet Earth (lithosphere) is typically divided into enormous (massive) slabs of solid rock (plates) that move over the asthenosphere, including the upper portion of the mantle.
<h3>The uses of the theory of plate tectonics.</h3>
- It can be used to explain the presence of magnetic anomalies on the ocean floor.
- It can be used to explain the geographical distribution of earthquakes and volcanoes.
- It can be used to explain the presence of glacial deposits in tropical areas.
- It can be used to explain the origin of mountains.

The difference between comparative advantage and absolute advantage is that: A. Comparative advantage measures opportunity cost and absolute advantage measures efficiency.
<h3>What is a comparative advantage?</h3>
A comparative advantage can be defined as the ability of a business firm or country to produce goods and services at a lower opportunity cost than their rivals (competitors) or trade partners.
<h3>What is an opportunity cost?</h3>
An opportunity cost is also referred to as alternative forgone and it can be defined as the value, profit or benefits that are given up and forfeited by an individual or business firm, in order to choose or acquire something that is deemed most significant at a particular point in time.
In this context, we can infer and logically deduce that the difference between comparative advantage and absolute advantage is that comparative advantage measures opportunity cost and absolute advantage measures efficiency.

YES PLEASE!!! Can you solve this problem?
Explanation:
June is driving from brookline, massachusetts to brooklyn, new york. The cities are 200 miles apart. Pretend june lives in a world in which she encounters no traffic jams and can drive at a constant speed of 50mph the entire way. Consider the following function. the distance june has traveled, c, is a function of her driving time, t.
write a formula that describes this function
