Question 7 Consider the function f (x) = x + 6x 3 3 points How Did I Do? (a) Find the domain of f () Note: Use the letter U for union. To enter oo, type infinity with a lower case i. o Domain: (b) Give the horizontal and vertical asymptotes of f (x), if any. Enter the equations for the asymptotes. If there is no horizontal or vertical asymptote, enter NA in the associated response area. horizontal asymptote: vertical asymptote: (c) Give the intervals of increase and decrease of f (x). Note: Use the letter U for union. To enter oo, type infinity with a lower case i. If the function is never increasing or decreasing, enter NA in the associated response area. increasing: decreasing: Submit Assignment Quit & Save Back Question Menu - Next(d) Give the local maximum and minimum values of f (a). Enter your answers in increasing order of the a-value. If there are less than two local extrema, enter NA in the remaining response areas and the corresponding drop-down menu. Include a multiplication sign between symbols. For example, a . 7. f( )= Click for List f ( ) = Click for List (e) Give the intervals of concavity of f (x). Note: Use the letter U for union. To enter oo, type infinity with a lower case i. If the function is never concave upward or concave downward, enter NA in the associated response area. concave upward: concave downward:(f) Give the inflection points of f (z). Enter your answers in increasing order of the x-coordinate. If there are less than two points of inflection, enter NA in the remaining response areas. Include a multiplication sign between symbols. For example, a . 7. )
