Can someone plz give me the answer for this question?

see explanation

Step-by-step explanation:

Given

f(x) = - 4

let f(x) = y

y = - 4

Switch x and y and solve for y, that is

x = - 4 ( add 4 to both sides )

x + 4 =

Take the ln of both sides

ln(x + 4) = ln = 2y = 2y

Divide both sides by 2

y = , that is

(x) =

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
