If my answers are wrong, please correct them. Thank you somuch.

1. The function f(x) = 7^-x is an exponential growth function.FALSE
2. The graph of y = 3^(x+1) is obtained by shifting the graph ofy=3^x one unit to the
left. TRUE
3. The logarithmic and exponential functions are inverse functionsof each other. TRUE
4. The logarithmic form of the equation 2^4 = 16 islog24 = 16. FALSE
5. If log9X = -2, then x = 1/81 TRUE
6. The graph of a logarithmic function with any base a, (a > 0)passes through the
point (1, 0).   FALSE
7. The expression ln(x/5 + y/5) = lnx + lny-ln5 is a trueexpression.   TRUE
8. The expression lne + 3log3 2 = 3 is a trueexpression. TRUE
9. If a fair die is rolled then the sample space has 6elements.   TRUE
10. The probability that an event E will not occur is 2/9, then theodds in favor of E
occurring is 2 : 7.    FALSE
.

Explanation / Answer

#6 is true...for example Ln(1) = 0 #7 is false There is no rule of the form Log(A+B) only Log(A*B) and Log(A/B) #10 The PROBABILITY in favor is (7/9) but ODDS is a differentcalculation than probability...I cant remember how to caclulateodds from probability but I used an odds calculator on the internetand for a prob of (7/9) the odds ARE 2:7 thus the answer is true
