1. A relation is a set from x to a set y is called a function if each element of c is related to exactly one element in y. That is,given an element c in c, there is only one element in y that x is related to.
2. You can set up the relation as a table of ordered pairs. Then, text to see if each element in the domain is matched with exactly one element in the range . if so you have a function
3. The domain is the set of all possible x-values which will make the function "work" and will output real y- values .When finding the domain , remember :the denominator (bottom) of a fraction cannot be zero .
4.

One term of a geometric sequence is a4=135. The common ratio is r=3. Write an explicit rule for the nth term.

Answer:

$a_{n} = 5 * 3^{n-1}$

Step-by-step explanation:

To find the nth term of a geometric sequence, you have the general formula:

$a_{1} *r^{n-1}$

where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):

135 = $a_{1} * 3^{4 - 1}$
