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

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
