let's bear in mind that an absolute value expression is in effect a piece-wise expression, namely it has a ± versions of the same expression.

Answer:
When the range is wide
Step-by-step explanation:
It’s s=-2 and s=2 because the absolute value makes both of the numbers be positive so either way it’s going to be 2+4=6
hope it helps you!!!!!!!!!!!!
Answer:
y = 3x + 2
Step-by-step explanation:
First you want to know what the slope intercept form is. y = mx + b. Now take two points from the table and put them in the equation and get the slope of 3. Now we have y = 3x + b. To find b we need to plug in any point into the equation. I chose (-1, -1). -1 = 3(-1). Solve and you get 2. Now we are left with y = 3x + 2
