Symmetrical functions can be about the x and y axis. Essentially, if we reflect the graph across the y or x axis, we get the same graph. Some other graphs can be reflected across both the x and y axis at the same time and be symmetrical. These can be classified as odd and even functions. You can test this by replacing x and y with -x and -y and simplify the equation. If the results comes out to be the same as the original, it is symmetrical across the origin.
Best of Luck!
If we divide the area we have to cover by the area of a piece, we will get the number of pieces needed:
6x > 4x+26+8
2x > 34<span>
so,
x > 17 </span>
The answer is 6/9 as if you multiply 2/3 by 3 you will get 6/9 so it has the same value
