1. A-SSE.A.1b Interpret expressions that represent a quantity in terms of its context. Interpret complicated expressions by viewing one or more of their parts as a single entity.
F-IF.C.7e Graph functions expressed symbolically, and show key features of the graph, by hand in simple cases and using technology for more complicated cases. Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude.
F-IF.C.9 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions.
F-BF.B.4a Find inverse function. Solve an equation of the form f(x) = c for a simple function f that has an inverse and write an expression for the inverse.

9. 1. What is the logarithmic form of the equation?

10. 100 2 log____ _____ = __ Remember: log = exponent 10 A. 100 = 102
If x = by, then logbx = y
Remember: log = exponent
100 2
log____ _____ = __ 10

11. B. 81 = 34
Remember: log = exponent 81 4
log___ ____ = ___ 3

12. C. 36 = 62
Remember: log = exponent
Log6 36 = 2

13. 2. What is the expontial form of the equation?

14. 25 5 2 If log5 25 = 2, then A. log5 25 = 2 If logbx = y, then x = by
_____ = ___ ___ 2

15. B. log3 81 = 4
If log3 81 = 4, then
81 = 3 4

22. log = exponent

23. 3. What is the value of the log?

24. y 32 = 8 25 = (23)y A. log832 = y 2•2•2•2•2 = (2•2•2)y
FACTOR both sides.
2•2•2•2•2 = (2•2•2)y
25 = (23)y

25. 25 = 23y
Hint: If ab = ac, then b = c.
__ __
5 = 3y OR

26. B. log5125 = y y
= 5
125
5•5•5 = 5y
53 = 5y

27. 53 = 5y
Hint: If ab = ac, then b = c.
3 = y OR

28. C. log4 = y y
= 4

29. -3 = 2y

30. -3 = 2y
__ __ OR
