7. The x - axis is a horizontal asymptote for the graph of y = ez. 8. log100 (10) = 2 11 9. If f(x) = log3 (x), then f 1 (x) = 3 10. The domain of f(x) = In(a) is (-co, co). 11. In e2.451 = 2.451 12. For any base a, where a > 0 and a # 1, log. (0) = 1. 13. The equations a + 1 = 2x + 3 and log(x + 1) = log(2x + 3) are equivalent. 14. The equations log(x - 2) = 4 and log(x) - log(2) = 4 are equivalent. 15. The exact solution to 3* = 17 is 2.5789. 16. If 27-3 - 32x+1, then x - 3 = log, (327+1)
