Example
graph y = log(x-2)-5
- Get the mapping rule (x+2,y-5)
- Get the V.A. in this case it is x = 2
- use Graphing Logarithms famous five
| x | y |
|---|---|
| 10^-2 | -2 |
| 10^-1 | -1 |
| 10^0 | 0 |
| 10^1 | 1 |
| 10^2 | 2 |
| with mapping rule (x+2,y-5) |
| x+2 | y-5 |
|---|---|
| 2.01 | -7 |
| 2.1 | -6 |
| 3 | -5 |
| 12 | -4 |
| 102 | -3 |
| You can use decimals. Dont do shit like 10^-2+2, make them decimal |
- Y intercept? X intercept?
- Domain? Range?(usually Y∈ℝ)
