determining a quadratic funct
which function has a vertex at (2, -9)?
lo ax) = -(x - 3)2
o f(x) = (x + 8)2
© f(x) = (x - 5)(x + 1)
o f(x) = -(x - 1)(x - 5)

‼️‼️‼️‼️‼️the pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is 440 f, find the pressure exerted when the temperature of the gas is 380°f. (show work)
