The intensity I of an earthquake is given by
I = I₀ 10ʳ where r the magnitude on the Richter scale, l₀ is the minimum intensity, and r = 0 is used for comparison. Find I, in terms of l₀,for an earthquake of magnitude 4.4 on the Richter scale.
f(x) = 1/3 x³ - 5x² - 11x - 7
f(x) = 2/3 x³+ 2x² -16x +4
