Use a comma to separate answers as needed.) List the interval(s}| on which the function is decreasing. E (Type your answer in interval notation. Use a comma to separate answers as needed.) List the interval(s}| on which the function is constant. E (Type your answer in interval notation. Use a comma to separate answers as needed.) ... A blouse that is size x in country A is size s(x) in country B, where s(x) = x + 4. A blouse that is size x in the country B is size t(x) in country C, where t(x) = x - 3. Find a function f(x) that will convert blouse sizes in country A to blouse sizes in country C. f(x) = (Simplify your answer.)4 fix + h] fix]: For the function x] Ex + 4. construct and simplify the difference quotient T. c:} f{x+h}|f[x} T2D (Simplify your answer. Use integers er fractions for any numbers in the expression} Find the variation constant and an equation of variation for the given situation. y varies inversely as x, and y = 35 when x = The variation constant is The equation of variation is y =Find an equation of variation in which y varies jointly as x and z, and y = 3 when x = 3 and z = 1. The equation of variation is y = . (Simplify your answer.)
