Express the function graphed below

9514 1404 393

Step-by-step explanation:

The line to the upper left has a slope of -1. If it were extended, it would intersect the y-axis at y=3, so its equation is ...

  y = -x +3

The line to the upper right has a slope of +1 and a y-intercept of 4, so its equation is ...

  y = x + 4

At x=-2, the function is defined as -2.

So, the piecewise definition is ...

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
