Derivatives. Find the derivative of the following functions. Note: It is not necessary to simplify. (a) h(x) = In(2x2 5x + 7) h'(x) = 111(4x 5) (b) g(x) = e'z"3 ' 5") gm = (6x2 _ 5)e2x35x Logarithms. Use the laws of logarithms to expand and simplify the following expression In 13x6 ) + In esx - 5x - In(13) The simplified expression is O 9In(x) O -10x O -3In(x) 10x O -9In(x) 8In(x) - 5x O 3In(x) O In(13) ( 75In(x) - In(13) None of the aboveA function f has the form f(x) = a + b In(x). Find f if it is known that f(1) = 6 and f(2) = 7. (Round the value of b to four decimal places.) f ( x ) =
