A quadratic function passes through the points (-1,3), (2, -4) and (5, 4), Which of the system of equations below could
solved in order to find the equation of the parabola?
( a - b + c =3 li a+b+c=3 li a - b - c=3 lia-b+c= -3
4a + 2b + c = -4 14a + 2b + c = -
4 4a + 2b - c = -4B 4a - 2b + c = 4
25a + 5b + c = 4 | 25a + 5b + c = 4 | 25a - 5b - c = 4 (25a - 5b + c = 4

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
