Classify the follwing as a constant , linear , quadratic and cubic polynomials
(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

To classify the given polynomials as constant, linear, quadratic, or cubic, we need to look at the highest degree (exponent) of the variable in each polynomial. Here’s the step-by-step solution:

### Step 1: Analyze each polynomial

1. **Polynomial: `2 - x^2 + x^3`**
- The highest exponent of `x` is `3`.
- **Classification:** Cubic polynomial.
