<em>The above represents the exponential function</em>
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 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:
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
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.
