hey :)

Ok ... here is how it goes :

f(x) = 10^x
therefore f^-1(x) :
swap x - y
therefore : x=10^y
then ...
f^-1(1) :
1 = 10^x
therefore x has to equal zero , as 10^0 = 1

Hope I helped :)

This question worth 1 mark, so it doesn't need working out. There is a rule in indices... Anything to the power of zero =1
