Math Problem Statement
please advise the correct answer
Complete the equation for the piecewise function graphed below.
Solution
The image contains a graph representing a piecewise function, and you are asked to complete the equation for .
Here’s the process to determine the equations for each segment:
1. Segment from to :
This is a linear segment with a decreasing slope. To find the equation:
- The endpoints are and .
- Using the slope formula .
- The point-slope form of a line is . Using the point and slope , the equation becomes:
So, for , the equation is .
2. Segment from to :
This is a constant function at . This means the function is simply for .
3. Segment from to :
This is another linear segment, this time decreasing. The endpoints are and .
- The slope is .
- Using point-slope form with the point :
So, for , the equation is .
