Need help with this problem really quick :)))

Complete parts (a) through (c) for the following function. f ( x ) = 2 + 14 x + 48 (a) Find intervals where the function is increasing or decreasing, and determine any relative extrema. b) Find intervals where the function is concave upward or concave downward, and determine any inflection points. (c) Graph the function, considering the domain, critical points, symmetry, relative extrema, regions where the function is increasing or decreasing, inflection points, regions where the function is concave upward or concave downward, intercepts where possible, and asymptotes where applicable. D. The function does not increase or decrease on any interval. Determine any relative extrema. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The function has a relative maximum at and a relative minimum at (Use a comma to separate answers as needed. Type ordered pairs.) O B. The function has a relative minimum at , but does not have any relative maxima. (Use a comma to separate answers as needed. Type an ordered pair.) O C. The function has a relative maximum at , but does not have any relative minima. (Use a comma to separate answers as needed. Type an ordered pair.) O D. The function does not have any relative extrema. (b) Find intervals where the function is concave upward or concave downward. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The function is concave downward on , but is never concave upward.
