Answer 1

Answer:

Step-by-step explanation:

If you enter all of these points in L1 and L2 in edit under your stat button on your calculator and then choose QuadReg from "calc" under the same stat button, you'll get a quadratic model:

$y=-.008x^2+.745x+13.472$

Not sure which of your choices this matches, but there you go!
