PLEASE HELP VERY IMPORTANT

Answer 1

`\hat{y}=0.246x^2-6.815x+47.062`

Explanation:

You don't need technology to figure this out.

Clearly, the multiplier 47 on the x^2 term is way too large, eliminating the 1st and 3rd choices. The general trend is downward, so the 2nd choice is inappropriate. The 4th choice is the only one that makes sense.
