Question

PLLSSS REALLY URGENT
If g(x)=3x+4, determine n that g(-3)=g^-1(n).

Answer 1

we have:

g(-3) = 3.(-3) + 4 = -5

`g {}^( - 1) (n) = (1)/(3n + 4)`

because

`g( - 3) = g {}^( - 1) (n)`

=>

`- 5 = (1)/(3n + 4) \\ \\ < = > - 5(3n + 4) = 1 \\ \\ < = > - 15n - 20 = 1 \\ \\ < = > n = ( - 21)/(15) \\ \\ < = > n = ( - 7)/(5)`
