Which statement describes how to determine if a relation given in a table is a function? A.) If none of the output values are repeated, the relation is a function.

B.) If none of the input values are repeated, the relation is a function.

C.) If any of the input values are equal to the output values, the relation is a function.

D.) If all the output values are paired with the same input value, the relation is a function.

B.) If none of the input values are repeated, the relation is a function.

Step-by-step explanation:

The input values in a function are it's x-values. The output values are the y-values.

Each x-value must relate to one y-value. If the 'x-values' are repeated, then the relation is not a function.

Option B should be correct.

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

1.) 21

2.) 0.453

3.) 1.5

4.) 48

5.) $ 22
