Use analytical and/or graphical methods to determine the largest possible sets of points on which the following function has an inverse. 3 f(x) = -2 | ..... List the intervals on which the function has an inverse. Make each interval as large as possible. B/21 1/21 (Use a comma to separate answers as needed.) 38%

E Tools Done plete any missing inputs or outputs for the following function: y= 3x-6 1.5 1.5 y

Find the largest open intervals on which the function is concave upward or concave downward, and find the location of any points of inflection. 3 f(x) = -a X-3 Select the correct choice below and fill in the answer boxes to complete your choice. (Type your answer in interval notation. Use a comma to separate answers as needed. Use integers or fractions for any numbers in the expression.) O A. The function is concave upward on and concave downward on O B. The function is concave upward on There are no intervals on which the function is concave downward. O C. The function is concave downward on There are no intervals on which the function is concave upward.
