Name: ____________________ Calculus Test #3 (Sectinos 4.4 – 5.5) 1. (10 pts.) Sketch the graph of ONE SINGLE function that satisfies all of the following properties: f (x) is odd, has a vertical asymptote at x 3 , lim f ( x) 2 , f ( x) 0 on 0, 3 3, , f ( x) 0 on 0, 3 and f ( x) 0 on 3, . 2. (15 pts.) Find the following limits: a. x2 2 x x 0 sin x lim x 1 b. lim x x x 3. (10 pts.) Estimate are doing. 2 1 e x dx using right-hand endpoints with 3 subdivisions. Draw a picture of what you 4. (15 pts.) Suppose the graph shown is the graph of f (x ) , the first derivative of f. Find the following for f (x) : (you need only write the x-value(s).) When is f (x) concave up? (STILL ASSUME THE GRAPH IS OF f (x ) ) When is f ( x) 0 ? (STILL ASSUME THE GRAPH IS OF f (x ) ) When is f (x) increasing? (STILL ASSUME THE GRAPH IS OF f (x ) ) When is f ( x) 0 ? (STILL ASSUME THE GRAPH IS OF f (x ) ) When does f (x) have any maximum values? (STILL ASSUME THE GRAPH IS OF f (x ) ) When does f (x) have any minimum values? (STILL ASSUME THE GRAPH IS OF f (x ) ) When does f (x) have any inflection points? (STILL ASSUME THE GRAPH IS OF f (x ) ) Integrate the following: a. (5 pts) b. (5 pts) x dx 4x 9 (t 1) 2 t2 dt c. (5 pts) 2 x 3 dx 0 d. (5 pts) sec 3 tan d 5. a) (5 pts.) Explain in words what 2004 f (t )dt represents if f (t ) is the rate at which the world’s 2000 population is growing in year t , in billions of people per year. b) (5 pts.) If w(t ) is the growth rate of a child in pounds per year, write a definite integral that expresses the total amount of weight a child gains from the time the child is 2 years old to 5 years old? What units will the integral have? 6. (15 pts.) a. Change the following integral using the definition of the integral (make into a limit of sums), using right hand endpoints 3 1 x2 1dx . You may need one or more of the formulas written on the board to evaluate. b) Check your answer from part a by evaluating the integral Theorem of Calculus 3 1 x2 1dx using the Fundamental 7. (10 pts.) Let g ( x) f (t )dt x , where f is the function whose graph is shown. 0 a. At what values of x do the local maximum and minimum values of g occur? b. Where does g attain its absolute maximum? c. On what intervals is g concave down? d. On what intervals is g concave up? Extra Credit: Which of the following areas are equal? Why? (You must explain your answer, guessing will NOT give you any credit)
