The equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.

<h3>What is a quadratic equation ?</h3>

Any equation of the form  \rm ax^2+bx+c=0 Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

The standard form of a quadratic equation:

\rm y =ax^2+bx+c

Plug x = 0 and y = 6

6 = c ...(1)

Plug x = 1, and y = 10.7

10.7 = a + b + c ...(2)

Plug x = 2 and y = 14

14 = 4a + 2b + c  ...(3)

After solving equation (1), (2) and (3) we get:

a = -0.7

b = 5.4

c = 6

\rm y =-0.7x^2+5.4x+6

Thus, the equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.
