Inverse Of Functions

I use a certain way to find the inverse of a function.

Replace H(x) with y.

y=2x+1

Replace y and x.

x=2y+1

Find y.

x-1=2y

Divide both sides by two.

x-1/2=y

The Answer Is

 $h^{ - 1} (x) = \frac{x - 1}{2}$

Therefore, the area of actual picture on the wall.

$=\frac{8}{2} \times \frac{6}{2}$

$=4\times 3\\=12$

So, the area of actual picture on the wall is 12 square feet.

for A you should take each plotted point and change the sign of the x values. for example (-1,3) should become (1,3) and (-4,4) should become (4,4)

for B take each point and flip the variables and x's sign. (-1,3) should become (3,1)

for C take every x value and subtract 2. (-1,3) should become (-3,3)

for D take each point and flip the variables and y's sign. (-1,3) should become (-3,-1)
