(i) `2-x^(2)+x^(3)` (ii) ` 3x^(3)` (iii) `5t - sqrt(7)`
(iv)`4-5y^(2)` (v) 3 (vi) 2+x
`(vii) y^(3)-y` (viii) `1+x+x^(2) (ix)t^(2)`(x) `(sqrt(2))x-1`

Explanation

(i) Polynomial `2-x^(2)+x^(3)` is cubic polynomial , because maximum exponent of x is 3.
(ii) Polynormial ` 3x^(3) ` is a cubic polynomial , because maximum exponent of x is 3.
(iii) Polynomial `st -sqrt(7)` is a linear polynomial, because maximum exponent of t is 1.
(iv) Polynomial `4-5y^(2)` is a quadratic polynomial , because maximum exponent of y is 2.
(v) Polynomial 3 is a constant polynomial , because the exponent of variable is 0.
(vi) Polynomial `2+x` is a linear polynomial , because maximum exponent of x is 1.
(vii) Polynomial `Y^(3)-y` is cubic polynomial ,because maximum exponent of x is 2.
(viii) Polynomial `1+x+x^(2)` is a quadratic polynomial, beacause maximum exponent of x is 2.
(ix) Polynomial `t^(2)` is a quadratic polynomial , beacause maximum exonent of t is 2.
(x) polynomial `sqrt(2)x-1` is a linear polynomial , because maximum exponent of x is 1.
