10. The intensity I of an earthquake is given by 1 =10 10R where R the magnitude on the Richter scale, lo is the minimum intensity, and R=0 is used for comparison. Find I, in terms of lo, for an earthquake of magnitude 4.4 on the Richter scale f ( x) = = 3 X -5x2 - 11x +7 3 f ( x ) = 2 2 3 + 2X -16x +4 X + 27
