The table gives some values of \(y=2^x\).
\(x\)
-2
-1
0

2
3
\(y\)
0.25

2
8
Copy and complete the table.
On a sheet of graph paper, using a scale of 2 cm to 1 unit on the \(x\)-axis and 2 cm to 2 units on the \(y\)-axis, draw the graph for \(-2\le x\le3\).
Use your graph to estimate the value of \(x\) when \(y=5\).
