15 The value of the function f (2) is when = -5 and is when I = 3. What is the equation of the function?
O f () = + 20
O f (x) = 10 +35
O f(x)=11-20
O f () = -12-1
(will give brainliest)

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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
