Question
Before sketching the function, it will be helpful to find an
expression for x, in terms of y.
The function is
y = log4(x – 3) + 5.
This can also be written as follows.
= log4(x – 3)
Now rewrite this equation in exponential form.
= x - 3
Isolate the variable x.
+ 3 = x
Now use the appropriate expression to calculate the missing
values in this table. (Round your answer to five decimal places.)
x 3.00098
3.01563 3.06250
3.25000
