A relation is a function if it passes the vertical line test. That graph in a coordinate plane is just a sin wave that is spread out. If you run a perfectly vertical line through the graph at every place on the graph, the line you draw will only go through the graph at one place every time. That makes it a function. It's not a one-to-one function cuz it fails the horizontal line test, but it is a function!

Answer:
Step-by-step explanation:
Given:
Two equations are given.
------(1)
----------(2)
Solve equation 1 for y.
-----------(3)
Now, we substitute y value in equation 2.
Now, we substitute x value in equation 1.
Therefore, the value of x and y is
