Answer:

f^{-1}(x)=3x-6

Step-by-step explanation:

Let's replace f(x) with x and replace x with f^{-1}(x) ad solve.

x=1/3*f^{-1}(x)+2

x-2=1/3*f^{-1}(x)

f^{-1}(x)=3(x-2).

\boxed{f^{-1}(x)=3x-6}

Given that these simultaneous equations
Tatiana [17]

The value of k is(3\sqrt{ 10})/2

<h3>How to solve the simultaneous equation?</h3>

Given:

x-y=k.............(eq i)

2x²+y²-15..............(eq ii)

We would make y the subject formula in eq ii

2x²+y²-15= 0

2x² + y²= 15

y²= 15-2x²

y= \sqrt{15-2x^2}...........(eq iii)

Substitute the value of y into eq i

x-(\sqrt{15-2x^2}= k

x- (\sqrt{15} - 2x= k

k= (3\sqrt{ 10})/2
