The equation that model a quadratic function is: y=0.9673x²-0.8475x+10.4334
Step-by-step explanation:
A quadratic function has the form of ;
f(x) = ax²+bx+c where a, b and c are real numbers and a≠0
For this case, equation y=0.9673x²-0.8475x+10.4334 models a quadratic function where a>0 thus the parabola opens upwards

20 high x 18 long = 360 square feet
3 windows x (4 high x 3 long) = 3 windows x 12 square feet = 36 square feet
360 - 36 (because we obviously don't paint windows) = 324
324 square feet to paint on one wall
