Find all critical points for the function 2x+9 \"km on (700, 00) and then list them (separated by commas) in the box below. List of critical points: | The function f(a:) : 3503 95::2 1353: + 7 is increasing on the inverval (00, A] U [3, co), and decreasing on the interval [A,B]. A: andB= See Example 1 page 155 for a similar example. The function 7 m i 4+3:2 9(w) is increasing on the interval [A, B] and decreasing on the interval (00, A] U [3, 00). A : and B : See Example 2 page 156 for a similar example. The function f(:13) : 23:3 7 6:122 7 903: + 7 is increasing on the interval (700, A) U (B, 00) and decreasing on the interval (A, B). A: andB: f is concave up on (C, 00) and concave down on (00, C). 0: See Example 3 page 157 for a similar example. The function g(z) = 9 + 2 2 is concave up on (A, B) U (C, co) and concave down on (-0, A) U (B, C). A B , and C = See Example 4 page 157 for a similar example.Find the critical point and the local extreme value of the function f(m) = 2m2 7 5m + 3 on (foo, 00). The critical point is :1: = C] . The local extreme value is f(m) = C]. See Example 1 page 163 for a similar example. Find the local extreme values of f(:L') : 3563 9:122 2163: + 7. The local minimum value is and the local maximum value is Note: Local minimum value refers to the value of the function at the local minimum. See Example 2 page 163 for a similar example. Consider the function f(:c) = (sin 22:)4/5 on (717/12, 17/3). The critical points of f are
