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

Step-by-step explanation:
Answer:the price for the item now it's 6.75
Step-by-step explanation:
Origin price is 45=100% after reduction comes to 85% =x
X stands for the unknown value of the reduction therefore
45=100%
X=85%
45*.85=100x
After calculation you realised the value of x reduction value it's 38.25
Hence, original price is 45 your less from the value reduced 38.25 therefore the value of the item is 6.75
