First problem: 10x^2-21y^2/18xy
second problem: 13m-4n/10
To solve this problem, you must follow these steps:
1. Multiply the graph by -1 (That will reflect the function towards the -y axis).
2. Add 5. That will move the function upwards and you will obtain y=5 as its cut point with the y axis.
You can know the graph of a function by knowing the graph of the function "father" and applying the corresponding transformations, until turning it into the function studied.
The graph of the function f(x)=<span>|x| </span>has the shape of a cone that passes through the point (0,0).
