Which set of ordered pairs could be generated by an exponential function?
2 answers:
<u>ANSWER</u>
(0, 1), (1, 3), (2, 9), (3, 27)
<u>EXPLANATION</u>
The first and third options are completely out because the y-value of an exponential function is never zero.
For the second option the y-values has no geometric pattern or common ratio.
For the last option, we can observe the following pattern
:
:
The correct choice is the last option

Answer:
would be
when
.
Step-by-step explanation:
The question states that varies "inversely" as
. In other words, there is a non-zero number
(a constant) such that:
.
The challenging part is to find the value of in this equation.
Given that when
, replace the
in this equation with
and
with
. This equation should still be valid:
.
Solve for :
.
Hence, the relation between and
becomes:
.
Find the value of when
by replacing the
in this equation with
.
.
In other words, the value of would be
when
.
