In the sales comparison approach, using comparables that are five and 15 years old when appraising a subject that is 10 years old is an example of what?

a - base

b - exponent

so,

the one below it is a function

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

i think it’s c i believe
