Question

The function g is defined by g(x) = 8x-x^2 for x>=4
State the domain and range for g^-1

Answer 1

find the derivative using that: f' =1/g'
the domain will be everything that's is alowed for f'

Answer 2

So how do you find g^-1 anyway?

Answer 3

u can't expres it in explicit form...

Answer 4

So how do you find it? Answer says domain = x>=1 and the range is g^-1(x)>=4
