Answer:
Option c.
Step-by-step explanation:
It is given that the piecewise function represents the Social Security taxes for 2009.
We need to find Rachel's security tax if she earned $102,000 in 2009.
Since 102,000 lies in , therefore
Put x=102000.
So, the Social Security tax is $6324.
Therefore, the correct option is c.
Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:
So we need to find the entire interval at which this function positive. Put another way:
By using graphing tool, we get the graph shown below. As you can see:
- The function decreases from
- The function increases from
- The graph of the function is a parabola that opens up.
But what is really importan in this problem is that:
- The function is positive over the interval
At this interval the function is positive, that is,
Standard equation of the graph of a parabola:
