Question 1:

(1 point) Consider the function f(x) = 3x + 2351. Note that this function has no inflection points, but f \" (x) is undefined at x = B where B: For each of the following intervals, tell whether f(x) is concave up (type in CU) or concave down (type in CD). (00, B): (B, 00): (1 point) Let f(x) = x4 7x3 + 2x 6. Find the open intervals on which f is concave up (down). Then determine the x-coordinates of all inflection points off. 1 . f is concave up on the intervals -23x-6 2. f is concave down on the intervals 3. The inflection points occur at x = Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (inf, 2), (3,4), or the word "none". In the last one, your answer should be a comma separated list of x values or the word "none". \f(1 point) A table of values for f, g, f ', and g' is given below: 1 3 2 4 6 2 1 8 5 7 3 7 2 7 9 (a) If F(x) = f(f(x)), find F'(2). (b) If G(x) = g(g(x)), find G'(3). (a) F '(2) = (b) G'(3) =
