Logarithms. Use the laws of logarithms to expand and simplify the following expression In 13x3 ) + In/ esx - 3x - In(13) The simplified expression is 10In(x) O -10In(x) O -In(x) - 3x 32In(x) - In(13) 6x O 4In(X O -6x In(13) O -4In(x) O None of the aboveSDT. Let f(x) = 2x3 - 9x2 + 12x + 42. Classify the critical point x = 2 of f(x) using the Second Derivative Test. (a) The second derivative at x = 2 is f"(2) = (b) The critical point x = 2 is unknown because the test is inconclusive a minimum a maximum
