Answer:
C
Step-by-step explanation:
The general rule for the quadratic function is
Use the data from the table:
We get the system of three equations:
Subtract these equations:
From the first equation
Substitute it into the second equation:
So,
The quadratic function is
leg1² + leg2² = hypotenuse²
AC² + BC² = AB²
2² + 5² = c²
1/9
120/1080 can be simplified to 1/9
