Let f(x)=log(x^2-2x) and g(x)=x/x-1. which expression represents (fog)(x)?

log(x^3-2x^2)/x-1

xlog(x^2-2x)/x-1

log(x^2-2x)/log(x^2-2x)-1

log(x^2-2x(x-1)/(x-1)^2)

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

Aboat costs 19200 and decreases in value by 12% per year. how much will it cost in 5 years

Someone answer this asap for the function f(x) and g(x) are both quadratic functions. f(x) = x² + 2x + 5 g(x) = x² + 2x - 1 which statement best describes the graph of g(x) compared to the graph of f(x)? a. the graph of g(x) is the graph of f(x) shifted down 1 units. b. the graph of g(x) is the graph of f(x) shifted down 6 units. c. the graph of g(x) is the graph of f(x) shifted to the right 1 unit. d. the graph of g(x) is the graph of f(x) shifted tothe right 6 units.
