1) Find the intervals interval or if the answer the following questions for these 3 two functions; a) f(no) = x+9x02-2120+1 b) f(x) = e On 370 te -31 which F is increasing or decreasing. Enter your answer as union of intervals. capital letter 'U' for union. a an Use Enter "1 {}" function is never increasing or decreasing. Increasing: Decreasing: 2) List the x-values of any Jocal extrema, separated by commas. Enter 'N' if there are none, Local maxima: Local minima 3) Find the intervals On which fis concave "{}" up or Concave down. Enter if the function is never concave up or down. Concave up: Concave down: 4) List the x-values of of , inflection, separated by commas. any points Enter 'N' N' if there are none, Points of inflection: 1) Find the intervals interval or if the answer the following questions for these 3 two functions; a) f(no) = x+9x02-2120+1 b) f(x) = e On 370 te -31 which F is increasing or decreasing.
