Find the domain of f(x) = -4x + 2 for the range {-5, 2, 6, 18).
Flauer [41]

Answer:

Step-by-step explanation:

calculate x for this equation

f(x) = -5 : -4x +2 = - 5 so : -4x =-7        x = 7/4

f(x) = 2  : -4x +2 = 2   so : -4x =0        x = 0

f(x) =6  : -4x +2 = 6  so : -4x =4       x = -1

f(x) = 18  : -4x +2 = 18  so : -4x =16        x = - 4

the domain is : D = {7/4, 0, -1, -4}
