I still don’t understand can someone give a helping hand?
Fofino [41]

Answer:

A

Step-by-step explanation:

A, B, C, and D, are all functions. the " { " is saying that those functions can are different at different points. For A the function is A= -x-2 when x< 2 and then A=x+4 when x\geq -2. At the point x=-2 you can see that the function on the graph is going in two different directions but it stops at x=-2.

Based on the graph you can see that the line on the left has a slope of -1 and if it kept going it would cross the y-axis at y=-2, therefore the equation for the first line is y =-x-2 when x

The second line on the right side has a slope of 1 and crosses the y-axis at y=4 so the equation for that line is y=x+4 when x\geq -2.

The only answer that matches these requirements is A
