transformation(急)

1. Reflection by y=x =====> the inverse function

The inverse function of 10^x is log x, hence the new graph obtained is y=log x

2. Replace x by (-x), [This is the reflection about the y-axis]
y=10^(-x)
y= [ 10^(-1) ]^x
y = (1/10)^x

So the transformation is reflection about the y-axis
