1. a. Given 4 f ( x) 2 x , g(x) = 3 - 2x, find the composite function (f o g)(x) and simplify. b. Find (f o g)(-5) where f(x) = -3x-1, g(x) = x2 - 3 2. Solve for a: 2a 2 a 15 a 9 3. Solve, and express the answer in interval notation: | 8 - 5x | 12 4. Express as a single logarithm: log (x + 2) + log 1 - 3 log y 5. The percentage score on a test varies directly as the number of correct responses. Rita answered 24 questions correctly and earned a score of 60%. What would her percentage score have been if she had answered 34 questions correctly? 6. Multiply and simplify: (8 + i)(5 + 3i). Write the answer in the form a + bi, where a and b are real numbers. 7. Solve the inequality, and write the solution in interval notation: x7 0 x 1 8. Find the exact value of the logarithm without using calculator: 1 log 2 ( ) 16 9. Solve for x: log2 (5x-4) = 4 10. Suppose $2,800 is invested in an account at an annual interest rate of 4.7% compounded continuously. How long (to the nearest tenth of a year) will it take the investment to double in size
