Let f(x) = -5 + 6x - a . Find the open intervals on which f is increasing (decreasing). Then, determine the x-coordinates of all relative maxima (minima). 1. f is increasing on the intervals 2. f is decreasing on the intervals 3. The relative maxima of f occur at x = 4. The relative minima of f occur at = = 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 two, your answer should be a comma separated list of a values or the word "none".Let f(x) = x(x - 7vx) Determine the intervals on which the given function is concave up or down and find the point of inflection. (Help with interval notation.) The x-coordinate of the point of inflection is In the next two questions give the largest interval in the domain of f that fits the description. The interval on the left of the inflection point is On this interval f is ?? The interval on the right of the inflection point is On this interval f is ??Consider the function below. f(x) = x'+12x + 48x -56 Answer the questions below. Part 1: Enter your answers in interval notation. If the set is empty, type DNE. On what interval is the function f concave-up? On what interval is the function f concave-down?Consider the function below. 4 f(I) = - x2 + 16 Answer the questions below Part 1: Enter your answers in interval notation. If the set is empty, type DNE. On what interval is the function f concave-up? On what interval is the function f concave-down?Consider the function below. f(I) = 3- 91- + 24x - 17 Answer the questions below Part 1: Enter your answers as a list. If the set is empty, type DNE. For what numbers does f have a critical number?The following shows graphs of three functions, A (in black), B (in blue), and C (in green). If these are the graphs of three functions f, f', and f", identify which is which. (Click on the graph to get a larger version.) (For each enter A, B or C). f = :s' =:"=0Consider the function f(x) = 2x*+ 923 -60x + 5. Find the point where the local minimum of this function occurs. Answer: Find the point where the local maximum of this function occurs
