print poly.index(element), element, finalResult

YOUR CODE:
`0 3.0 3.0`
`1 4.0 -33.0`
`1 4.0 -69.0`
`3 2.0 -1527.0`
`4 0.0 -1527.0`
`-1527.0`


MY CODE:
`0 3.0 3.0`
`1 4.0 -33.0`
`2 4.0 291.0`
`3 2.0 -1167.0`
`4 0.0 -1167.0`
`-1167.0`

Since elements at index 1 and 2 are same, your code doesn't increment the index.
Use this code:

def evaluatePoly(poly, x):
    value = 0
    for index in range(0, len(poly)):
        value += (poly[index] * (x ** index))
    return float(value)
