Question

Hello, the question is in the picture (ignore b sorry)

Answer 1

The fuction graphed is

`y=\text{log}_(10)x`

Part A

The point

`(100,2)`

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.

`\begin{gathered} y=\log _(10)x \\ \text{put }y=5 \\ \text{Then} \\ \log _(10)x=5 \end{gathered}`

Simplify by changing to indices, we have

`\begin{gathered} \log _(10)x=5 \\ x=10^5 \\ x=100\text{ 000} \end{gathered}`

Hence

The graph will meet the line y=5 when x =100 000
