Answer:

Part A- yes, because all 3 sides are Equal (each side is 5)

Part B- yes, each rectangle has the dimensions 12*5

Part C- yes- since the sides are 5 and 12 you can determine that the diagonal is 13, using they Pythagorean theorem $a^{2} +b^{2} =c^{2}$

$5^{2} +12^{2} =13^{2} \\25+144=169$ - true statement, so the lateral sides are rectangles, because the corners are 90

Part D- $4\sqrt{2}$ (it is a 45-45-90 triangle- so the hypotenuse is the side length times $\sqrt{2}$

Part E- the diagonal face as the largest area- dimensions are $4\sqrt{2} * 12\\$

the area would be $48\sqrt{2}$

Describe the end behavior of the graphed function

You have to consider the “ends” of the x-axis, the far right (for infinitely large values of x) and left (for infinitely small values of x) of the graph.

From the diagram above you can see that:

When $x\rightarrow -\infty,$ then $y=f(x)\rightarrow 1$ (notice that as the values of x get smaller and smaller, the graph gets closer and closer to the line y=1);
When $x\rightarrow \infty,$ then $y=f(x)\rightarrow 1.$ (notice that as the values of x get larger and larger, the graph gets closer and closer to the line y=1).
