Question

Which graph represents the function f(x) = |x| - 4

Answer 1

Step-by-step explanation:

let's think about it logically :

|x| can only be positive, from 0 to +infinity.

but the second part "- 4" will bring the result for small x values into the negative realm.

x = 0 gives us f(x) = -4.

x = 4 gives us f(x) = 0

x = -4 gives us f(x) = 0

so, if is the 3rd graph (bottom left).
