Solution
To determine whether the equation
defines
as a function of
, we can solve for
in terms of
.
Starting with the equation:
We can isolate
by subtracting
from both sides:
This equation expresses
as a single output for each input
. For any given value of
, there is exactly one corresponding value of
.
Since
can be expressed as a function of
(specifically,
), we conclude that:
Thus, the answer is:

Bonus Knowledge
To determine if
is a function of
from the equation
, we can rearrange it to solve for
:
. This equation clearly defines
in terms of
, meaning for every value of
, there is one unique corresponding value of
. So, yes,
is indeed a function of
.
Now, if we were to graph the equation, it would yield a straight line descending from the y-intercept of 25 down to the x-axis at 25. Every horizontal line intersecting this graph would only touch it at one point, further confirming that
has a unique value for each
. Have a go at plotting it and see the beauty of linear functions in action!
