The onetoone functions g and h are defined as follows g 9 7

The one-to-one functions g and h are defined as follows. g = {(-9, -7),(-8, 2), (1, 7), (2, -8)} h(x) = 3x + 4 Find the following.

Solution

given g(-8)=2 so g^-1(2)=-8

h(x)=3x+4

let y=3x+4

interchange x,y

x=3y+4

x-4=3y

y=(x-4)/3

h^-1(x)=(x-4)/3
