Question

WILL MARK BRAINLIEST!

which quadratic function best fits this data?

x y
1 350
2 539
3 678
4 875
5 690
6 502

y=−9.16×2+73.04x+183.3

y=9.16×2−73.04x+183.3

y=9.16×2+73.04x+183.3

y=−9.16×2−73.04x+183.3

    Answer:

    y= −9.16x²+73.04x+183.3

    Values increase till x = 4 and then decrease which means thus curve has a maximum turning point around 4.

    Coefficient of x² should be negative

    because max to (concave down)

    x = -b/2a should be around 4

    x = -73.04/(2×-9.16) = 3.987
