SOLUTION
The fuction graphed is
[tex]y=\text{log}_{10}x[/tex]
Part A
The point
[tex](100,2)[/tex]
Is located on the graph beause the graph passes through the point, hence thier is need to locaye it on the graph.
Part C
For we to know when the meet y=5, we substitute 5 for y in the given equation and obatain the value of y.
[tex]\begin{gathered} y=\log _{10}x \\ \text{put }y=5 \\ \text{Then} \\ \log _{10}x=5 \end{gathered}[/tex]
Simplify by changing to indices, we have
[tex]\begin{gathered} \log _{10}x=5 \\ x=10^5 \\ x=100\text{ 000} \end{gathered}[/tex]
Hence
The graph will meet the line y=5 when x =100 000
