Two functions f and g are defined on the set R of real numbers by f(x) = 2x - 1 and g(x) =x² + 1. Find the value of og (3)

Step-by-step explanation:

To obtain the inverse of f(x)

let y = f(x) and rearrange making x the subject, that is

y = 2x - 1 ( add 1 to both sides )

y + 1 = 2x ( divide both sides by 2 )

= x

Change y back into terms of x with x = (x) , thus

(x) =

Evaluate g(3) and substitute the value obtained into (x)

g(3) = 3² + 1 = 9 + 1 = 10, then

(10) = =

x=12 units bd= 10 units
