with a b c or d

The table shows the mass of a substance decreasing over a period of time during a chemical experiment. Identify a quadratic model for the mass Af, given the time Then use the mode! to predict the mass at t= 11 seconds Time (s) Mass (9g) 2 94.8 5 87.9 8 81.3 OQ) M(x) = -0.02x? - 2.42 + 99.57 M(11) = 129 9 ) M(x) = 0.02x7 - 2.42x + 99.57 M11) * 759 ) M(x) = 0.02%? - 2.42% + 99.57 M(I1) = 129 g .
