Which graph represents the function f(x)=-|x|-2 ?
Elden [556K]

Answer:

The graph of given function is shown below.

Step-by-step explanation:

The absolute parent function is g(x)=|x|. The graph of parent function is a V-shape d and vertex of the function is origin.

The given function is

f(x)=-|x|-2              .... (1)

The vertex from of an absolute function is

f(x)=a|x-h|+k          .... (2)

where, a is a constant and (h,k) is vertex of the function.

From (1) and (2) we get

a=-1,h=0,k=-2

The value of a is -1. The value of a is negative it means the graph of parent function reflect across x-axis.

The vertex of the function is (0,-2). It means the graph of parent function shifts 2 units down.

The graph of given function is shown below.

Fed [463]

Answer:

Step-by-step explanation:

He will actually need to wait for 12 weeks. And that is because if you look at the multiples of 6 and 4 and you'll notice that 12 is the lowest common multiple between them. So you start counting from 6 and 4 at the same time until you notice the LCM of these two numbers then on which ever you number you settle on is how long he will need to wait.
