Analyze the graph of f(x)=-2×5/3+4×4/3 (Answer Format: Unless the value is an integer, the answers are rounded to the nearest thousandth.) a) The function is increasing over the interval(s) [BLANK-1] and decreasing over the interval(s) [BLANK-2]. b) The function is concave upwards over the interval(s) [BLANK-3] and concave downward over the interval(s) [BLANK-4]. c) The RMIN occurs at x value(s) =[BLANK-5] and the RMAX occurs at x value(s) =[BLANK-6] d) Point of concavity occurs at x value(s) = [BLANK-7] e) The x-intercept(s) occur at x=[BLANK-8]

Answer Format: Do not enter $ sign nor decimals. Each answer will be a whole number. An office supply company sells x mechanical pencils per year at $p per pencil. The price equation for these pencils is p=10 – 0.001x. Determine the revenue function (R=xp) and use it along with its derivative to find: a) how many pencils must be sold in order to maximize revenue. x=[BLANK-1] b) the maximum revenue. R = $ [BLANK-2] c) the price (p) that yields maximum revenue. p = $ [BLANK-3] Furthermore, suppose cost is C(x)=5000 + 2x. Use this and the above information to answer the following. d) how many pencils must be sold to maximize profit (P=R-C)? x=[BLANK-4] e) find the maximum profit. P = $ [BLANK-5]  

Give the RMIN and RMAX for the function f(x)=x+16x  . Give both the x and y value as an ordered pair. If none exist, list “none” for both x and y.  RMIN=([BLANK-1], [BLANK-2])  and RMAX= ([BLANK-3], [BLANK-4])

Given the function: f(x)=3x4x3-8 a) Identify the vertical asymptote(s) of the function. Vertical Asymptote(s): x=[BLANK-1] b) Identify the horizontal asymptote(s) of the function. Horizontal Asymptote(s): y=[BLANK-2] c) Does the graph have a slant asymptote? Type yes or no [BLANK-3] d) The equation of the slant asymptote is y=[BLANK-4] (oops, I gave away part c).  (Answer Format: If there are multiple answers, separate with a comma. Write fractions in fractional form. {Example: -2/9,7} If there are no answers, write none. Only give the numerical value(s).)

The percent of concentration of a certain drug in the bloodstream x hourse after the drug is administered is given by:  K(x)=2xx2+25   How many hours after the drug is administered does the concentration in the bloodstream reach  a maximum? Do not enter the units. Unless the answer is a whole number, round to the nearest tenth of an hr.

Consider the Second Derivative Test to answer the questions. Suppose f(x) is a polynomial function with critical numbers x=1, x=2, and x=3. When the second derivative was evaluated at each number, the following results occurred:  f”(1)=50, f”(2)=-50, f”(3)=0  . From this information we can conclude;

Give the RMIN and RMAX for the function f(x)=-2×3-6×2+48x-12 . Give both the x and y value as an ordered pair. If none exist, list “none” for both x and y.  RMIN=([BLANK-1], [BLANK-2])  and RMAX= ([BLANK-3], [BLANK-4])
