Question

Can someone please help me, with part B

Answer 1

Explanation:

let y = x+5/4

Interchanging x and y , we get ;

x = y+5/4

or, 4x = y+5

or, 4x-5 = y

or, g(x) -1 = 4x-5

Answer 2

In verse of B.g(x)=
`(x+5)/(4)` is:

4x-5

Answer:

Solution given:

B.g(x)=
`(x+5)/(4)`

let

g(x)=y

y=
`(x+5)/(4)`

Interchanging role of x and y

we get:

x=
`(y+5)/(4)`

doing crisscrossed multiplication

4x=y+5

y=4x-5

So

g-¹(x)=4x-5
