Enter the functions given below. Try to identify the part of the graph where the function is increasing or decreasing and the intervals of the related values of x.. Click on the checkmarks to check your answer. 1. f(x) = 2x^3-5x^2+2x-1 2. f(x) = (x+1)/(x-1) 3. f(x) = (x^2+3x+2)/x 4. f(x) = 2^x-x+x-1 5. f(x) =sinx*(x^2+x)/x
