During a manufacturing process, a metal part in a machine is exposed to varying temperature conditions. the manufacturer of the machine recommends that the temperature of the machine part remain below 132 ° f. the temperature t in degrees fahrenheit x minutes after the machine is put into operation is modeled by t = Â0.005x2 + 0.45x + 125. will the temperature of the part ever reach or exceed 132 ° f? use the discriminant of a quadratic equation to decide.
