Are the functions f(x) and g(x) inverse of one another?
1 answer:
<h2>Answer:</h2><h2></h2><h3>No!</h3><h2></h2><h2>Explanation:</h2><h2></h2>
The function doesn't have inverse because it doesn't pass the horizontal line test. This test tells us that a function
has an inverse function<em> if and only if</em> there is no any horizontal line that intersects the graph of
at more than one point. As you can see, from the graph of f (the red one), if you draw an horizontal line that passes through
then this line will touch the graph of f at three points, so the horizontal line test is not satisfied here. If you see the graph of g, this doesn't represent a function because there is at least one vertical line that touches the graph at more than one point, so this relation is not a function.

$1269.23
Step-by-step explanation:
Since Sarah is paid biweekly (every 2 weeks), and there are 52 weeks in a year...
÷
Sarah is being paid 26 weeks out of the year.
Divide 33,000 by 26 (I only list 4 places after the decimal):
÷
