Classify the following polynomial as linear,quadratic,or cubic: $4x^{2} - 49$.

Write the coefficient of $x^{2}$ in the following polynomial:
$3x^{3} - 8x^{2} + 14x - 5$

Classify the following as linear,quadratic,and cubic polynomials:
$(i)$ $x^{2}+x$
$(ii)$ $x-x^{3}$
$(iii)$ $y+y^{2}+4$

If $p(x) = x^{2} - 4x + 3$,then find the value of $p(2) - p(-1) + p(1/2)$. (in $/4$)

For the polynomial $\frac{x^{3}+2 x+1}{5}-\frac{7}{2} x^{2}-x^{6},$ write:
$(i)$ the degree of the polynomial
$(ii)$ the coefficient of $x^{3}$
$(iii)$ the coefficient of $x^{6}$
$(iv)$ the constant term

Determine the degree of the following polynomial:
$y^{3}(1-y^{4})$
