Find any relative extrema of the function. List each extremum along with the x-value at which it occurs. Identify intervals over which the function is increasing and over which it is decreasing. Then sketch a graph of the function. Fx)=1-3x Describe any relative extrema. Select the correct choice below and, if necessary, fill in the answer box(es) to within your choice. A. The relative maximum point(s) is/are and there are no relative minimum points. (Simplify your answer. Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) O B. The relative minimum point(s) is/are and the relative maximum point(s) is/are (Simplify your answers. Type ordered pairs, using integers or fractions. Use a comma to separate answers as needed.) () . The relative minimum point(s) is/are and there are no relative maximum points. (Simplify your answer. Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) () D. There are no relative minimum points and there are no relative maximum points. Identify any intervals over which the function is increasing or decreasing. Select the correct choice below and fill in the answer box(es) within your choice. O A. The function F(x) is increasing over the interval(s) and is not decreasing anywhere. (Type your answer in interval notation. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) O B. The function F(x) is decreasing over the interval(s) and is not increasing anywhere. (Type your answer in interval notation. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) O C. The function F(x) is increasing over the interval(s) and decreasing over the interval(s) (Type your answers in interval notation. Use integers or fractions for any numbers in the expressions. Use a comma to separate answers as needed.) Choose the correct graph below. Suppose that P is invested in a savings account in which interest is compounded continuously at 6.3% per year. That is, the balance P grows at the rate given by the following equation. dP = 0.063P(t) dt (a)Find the function P(t) that satisfies the equation. Write it in terms of P, and 0.063. (b)Suppose that $500 is invested. What is the balance after 3 years? (c)When will an investment of $500 double itself? (a) Choose the correct answer below. O A. P(t)=P(t)e0-063t O B. P(t)=0.063P,e! O C. p, = p(t)ed-083 O D. pw)= pOeO.Oest (b) The balance after 3 yearis | |. (Type an integer or decimal rounded to two decimal places as needed.) (c) The doubling time is year. (Type an integer or decimal rounded to two decimal places as needed.) Minimize Q = 4x? + 4y*, where x+y =8. x=[ | y= (Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) Find a) any critical values and b) any relative extrema. f(x) = x% 8x + 20 a) Select the correct choice below and, if necessary, fill in the answer box within your choice. (O A. The critical value(s) of the function is/are (Use a comma to separate answers as needed.) () B. The function has no critical values. b) Select the correct choice below and, if necessary, fill in the answer box(es) within your choice. O A. The relative minimum point(s) is/are and the relative maximum point(s) is/are (Simplify your answers. Type ordered pairs, using integers or fractions. Use a comma to separate answers as needed.) O B. The relative maximum point(s) is/are and there are no relative minimum points. (Simplify your answer. Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) O C. The relative minimum point(s) is/are and there are no relative maximum points. (Simplify your answer. Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) () D. There are no relative minimum points and there are no relative maximum points
