Question

Find the inverse of the function
f(x)=3x−6

A f−1(x)=13x−6

B f−1(x)=−23x

C f−1(x)=13x+2

D f−1(x)=−13x+12

Answer 1

Here,

f(x) = 3x - 6

Now,

let, y = f(x)

y = 3x - 6

Interchanging x and y,

x = 3y - 6

or, (x + 6)/3 = y

◆ y = (x + 6)/3

◆ f - 1(x) = (x + 6)/3

I hope it's help you...

Thanks♥♥
