2) y 3 x 2
3) y 2 x 3
x
4) Write an exponential function in the form of y ab whose graph passes through the
point (4,8) and (6,32).
If log b y x
5) log 2 8 x
6) log 10 100 x
7) log 10 4 x 3
then
y b x find x in questions 5 – 7
If log b M N log b M log b N and log 2 2 a log 2 3 b log 2 5 c then evaluate
questions 8 – 10
8) log 2 6
9) log 2 15
10) log 2 30
11) Explain the transformations happening to its parent function ( y 2 x ) for the function
y (2) x2 1
12) Since y log 2 x is the inverse of y 2 graph the function y log 2 x . (Use a
separate sheet of graphing paper.)
