Part 1 -Application Describe a \"real world\" situation that can be described by this function? What is the domain and what is the range of your situation? Be sure to label the axes. (hint: Try using time,speed. temperature. etc) 18. The transformation from f to 9 represents a stretch. (5 points) f(x) = J; and 90:) = Jo.4x Note: Use all lowercase letters in your response. 19. Find f(x) and g(x) so that the function can be described as y = f(g(x)). (5 points) 1 x2 y= +2 20. Conrm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (5 points) x+4 f : (X) 6 and g(x) = 6x - 4
