What is the inverse of the function f(x) = x + 2? h(x) = 18x – 2 h(x) = 9x – 18 h(x) = 9x + 18 h(x) = 18x + 2

A function g is the inverse of a function f if whenever y=f(x) then x=g(y). The inverse is usually shown by putting a little "-1" after the function name, like this: f-1(y)

In our case the function is f(x)=x+2. 

The inverse function of f(x) is h(x)=x-2

Multiplying this function with 9 gives: h(x)=9x-18

B (h(x) = 9x - 18)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

look at the picture i have filled out a table for it. hope this .
