Solution
(i) Here, the number of times the graph cuts the x axis is 4. Hence, it is the graph of a quadratic polynomial and its degree will be 4.
(ii) Here, the number of times the graph cuts the x axis is 5.
Hence, this is the graph of a polynomial with degree 5.
(iii) Here, the number of times the graph cuts the x axis is 3.
Hence, it is the graph of a cubic polynomial and its degree will be 3.
