Answer:

Option B

Explanation:

Given function is,

f(x) = -|x - 4| + 6

By using a graphing tool we can get the graph of the given function.

From the graph attached slope of the line drawn from
$x=-\infty$ to
x=4 is positive while slope of the line from
x=4 to
$x=\infty$ is negative.

Therefore, segment showing a positive slope will be increasing in the given interval
$-\infty<x<4$ .

Function 'f' is increasing in the interval
$-\infty<x<4$ .

Option B will be the correct option.
