Want is the inverse of the function f(x)=2x-10

f

−

1

(

x

)

=

1

2

x

+

5

Explanation:

f

(

x

)

=

2

x

−

10

→

Replace the

f

(

x

)

with

y

y

=

2

x

−

10

→

Switch the places of the x and the y

x

=

2

y

−

10

→

Solve for y

x

+

10

=

2

y

y

=

1

2

x

+

5

The inverse is

f

−

1

(

x

)

=

1

2

x

+

5

The inverse is

f^-1(x)=1/2x+5

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
