Question: An engine will stall when the fuel pressure falls below zero psi ie when P t is negative The fuel pressure at a given temperature

An engine will stall when the fuel pressure falls below zero

An engine will stall when the fuel pressure falls below zero psi ie when P t is negative The fuel pressure at a given temperature is modeled by the formula t 2 7 0 8 1 where t is measured in C Rounded to the nearest whole degree at what temperature will the engine stall Hint You may want to graph the polynomial function When the temperature is below 5 C When the temperature is above 5 C When the temperature is below 8 C When the temperature is above 8 C
