The degree of a polynomial is the highest power of the polynomial.
Graph 3 has an odd degree.
From the attachments, we have the following highlights
- The first graph crosses the x-axis, 4 times
- The second graph crosses the x-axis, 6 times
- The third graph cross the x-axis, 3 times
- The fourth graph cross the x-axis, 2 times
The above highlights mean that:
- Graphs 1, 2 and 4 have even degrees, because they have an even number of x-intercepts
- Graphs 3 have an odd degree, because it has an odd number of x-intercepts
Hence, graph 3 has an odd degree.
