The Quadratic curve-of-best-fit for the data in the table is given by the equation. 0.8, 2.7. 1.3, 6.1. 2.2, 9.4. 2.9, 9.4. 3.7, 33. 5.1, 49.9. A) y=0.8x^2 + 1.7x - 1.4 B) y=1.1x^2 + 2.2x - 1.2. C) y= 1.4x^2 - 2.9x + 1.0. D). Y=2.3x^2 - 2.4x + 3.5

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

your answer is  

a.
