No link answers please What is the quadratic regression equation that fits these data?

Number of seconds Height (in feet)
x. y
0. 11
1. 13
2. 13
3. 12
4. 9
5. 1

A. y = -3.07x^2 +0.41x + 15.65

B. y=19.61(0.69^2)

c. y= -2.34x^2 + 2.19x + 16.25

D. y = -1.11x^2 + 3.74x + 10.64

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
