Answer:
Step-by-step explanation:
We have to find a cubic function of x whose zeros are at x = √7, x = -√7 and at x = -4.
Therefore, the factors of the function will be (x - √7), (x + √7), and (x + 4)
Hence, the equation will be y = (x - √7) (x + √7) (x + 4)

⇒ (Answer)
The partial sum of a geometric sequence is
In your case a=3, so if we sum N terms of the sequence we have
We want this to me more than 1 million, so we have
Considering the log (base 3) of both sides, we have
So, starting from N=13, the sum of the first N terms will be more than 1 million
