. Question 1 -3 -2 The above is the graph of the derivative f "(x). How many critical points does the original function f(x) have?Question 2 A > The function f(x) = 2x- 24x- + 42x - 4 has two critical numbers. The smaller the is x = and the larger one is x =Question 3 Use the derivative of the function shown below to determine the open intervals in which the function is increasing or decreasing and any relative extrema, and the x-values at which the extrema occur. f(z) = - 727+45x -5 a) Find all the critical values for the given function. If there are not any critical values, record DNE in the answer box shown below. If there are more than one, list them separated by commas. b) Record the open intervals in which the function is increasing or decreasing. If there are more than one intervals in which a function is increasing or decreasing, use a comma to separate the intervals (e.g., (-5,7), (-3,5)). If there are no intervals, record DNE in the answer box. Be sure to use oo (two letter o's and not zeros) for infinity and -oo for negative infinity. Increasing: Decreasing: c) Record the relative maximum and minimum of the function and the x-values in which they occur. If there are more than one, list them separated by commas. If there are none, record DNE in the answer box. I-value(s) where the relative max occur: Relative Maximum: I-value(s) where the relative min occur: Relative Minimum:O Question 4 Consider the function in the graph to the right. The function has a maximum of at x The function has a minimum of at x The function is increasing on the interval(s): The function is decreasing on the interval(s): The domain of the function is: The range of the function is:Mark the critical points on the following graph. z'e- 5, 69 621 $52 483- 414 345 276 207 138 69- Clear All Draw: DotQuestion 6 The function f(x) = (6x + 7)e-3 has one critical number. Find it. XEQuestion 7 C The function f(x) = - 2x + 39r - 216x + 4 has one local minimum and one local maximum. This function has a local minimum at r = with value and a local maximum at r = with valueQuestion 8 The concentration of a drug t hours after being injected is given by C(t) = 0.6t 12 + 49 Find the time when the concentration is at a maximum. Give your answer accurate to at least 2 decimal places. hours.Question 9 > Consider the function f(x) = 4 -2x2, - 3
