Question

The voltage in a circuit is determined at various times, as follows:

time: 1 2 3 4 5 6 7 8 9

voltage: 1.3  2.3  3.3  4.1  4.4  5.4  6.1  7.2  8.0 

1- Fit a curve of order 3 through the data points

2- Plot this line along with the sample voltages, the sample points with red circuils and the curve with black color  

3- According to your curve, determine at what time the voltage would be 2.5 V.
