Part 1: Multiple Choice Assuming all variables are positive, use properties of logarithms to write the expression as a sum or difference of logarithms or multiples of logarithms. 1) logg 10~x 2 A) logg 10 - - logg x + logg y B) logg (10-Vx) - logg y C) logg y - logo 10 - - logg x D) logg 10 +- logg x - logg y 2) log 16x A) 16 + log x B) log 16 . log x C) 4log 2 +log x D) 2log 4 + log x Find functions f and g so that h(x) = (f . g) (x). 3) h(x) = 6 10x + 1 A) f(x) =6/~x, g(x)=10x+ 1 B) f(x) =6, g(x) =10 +1 C) f(x) =10x+1, g(x)=6 D) f(x) =6/x, g(x) =10x + 1 Find the domain of the function. 4) f(x) = log (x+5) A) (1, *) B) (0, ) C) (-5, 2) D) (5, x) Find the domain of the logarithmic function. 5) f(x) = In 1 x+3 A) (-3, *) B) (0, *) C) (1, # ) D) (3, * )
