A polynomial is factored using algebra tiles.

Answer:
B.(x + 1) and (x − 3)
Step-by-step explanation:
The upper side of the tiles show the expression (x + 1), and the left side shows the expression (x - 3) (see figure attached). In both cases, you have to consider how many +x or -x are (one +x in one case and three -x in the other case). If you multiply the factors, you get:
(x + 1)*(x - 3) = x^2 - 3x + x - 3
which is the expression made by all the tiles.

Step-by-step explanation:
If a function is bijective and 1-to-1, then it will have an inverse function. Consequentially, they will be symmetrical about the line , which is a diagonal line passing through the origin at a 45 degree angle.
None of the graphs look correct though, but it also seems that some options are cut out, so make sure to choose the correct graph given the characteristics I've previously described.
