'''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>

{| class="mw-collapsible mw-collapsed" style = "text-align:left;"
! Foundations
|-
|How would you find f(5) if f(x) = 2x + 1 instead?
|-
|Answer: we replace every occurrence of x with a 5. So
|- style = "text-align:center"
|
<math>\begin{array}{rcl}
f(5) &= &2(5) + 1\\
& =& 11
\end{array}</math>
|}

Solution:

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

{| class = "mw-collapsible mw-collapsed" style = "text-align:left;"
! Final Answer:
|-
|<math> \log_3(8) - 1</math>
|}
