Radiation from the sun heats the Earth's surface by means of rays that are trapped in the atmosphere and allow the Earth to have constant heat.

<h3>How is the Earth's surface heated?</h3>

The surface of the Earth heats up due to the sun's rays that hit it and when they enter the atmosphere they are reflected on the surface being trapped between the atmosphere and the surface.

Another important aspect to keep in mind is that the rays strike at different angles throughout the Earth, for example:

  • In the equatorial zone they affect directly, so this zone tends to be more quality than others in which the rotation and translation of the Earth cause the rays to enter in less or more quantity throughout the year.

Find the domain for the rational function f of x equals quantity x plus 1 end quantity divided by quantity x minus 2 end quantit
Elena L [17]

Answer:

(- \infty, 2), (2, \infty)

Step-by-step explanation:

Given the function:

f(x) = \dfrac{x+1}{x-2}

To find:

Domain of the function.

Solution:

First of all, let us learn about definition of  domain of a function.

Domain of a function is the valid input values that can be provided to the function for which output is defined.

OR

Domain of a function f(x) are the values of x for which the output f(x) is a valid value.

i.e. The function does not tend to \infty or does not have \frac{0}0 form.

So, we will check for the values of x for which f(x) is not defined.

For value to tend to \infty, denominator will be 0.

x-2\neq 0 \\\Rightarrow x \neq 2

So, the domain can not have x = 2

Any other value of x does not have any undefined value for the function f(x).

Hence, the answer is:

\bold{(- \infty, 2), (2, \infty)}     [2 is not included in the domain].
