Given graph is,
Question ImageWe know that the graph of linear polynomial always forms a straight line and represented by y=ax+b,  where a and b are real number and a0.
And the graph of a quadratic polynomial is a parabola.
Question ImageThe direction depends on whether  a>0 or a<0 and is represented by
y=ax2+bx+c,  where a0. The given graph is neither a straight line nor a parabola.
So, the graph is neither a linear polynomial nor a quadratic polynomial.
Hence, option (3) is correct.
