'''Question:''' Find f(5) for f(x) given in problem 1.

Note: The function f(x) from problem 1 is: <math>f(x) = \log_3(x+3)-1</math>

|How would you find f(5) if f(x) = 2x + 1 instead?
|}

Solution:

{| class = "mw-collapsible mw-collapsed" style = "text-align:left;"
! Step 1:
|-
|Replace any occurrence of x by 5, so <math>f(5) = \log_3(5 + 3) - 1 = \log_3(8) - 1</math>
|}
