Question

The function f(x)=-\x-4/+6 is increasing
through the interval -
A. 6 C. 4 B. -00< x < 4
D. 4 :)

Answer 1

Answer:

Option B

Step-by-step 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.
