Which Graph represents y as a function of x?
it for unit 2 lesson 13
i could not post the picures srry
Thank you for your help blank
To determine which graph represents y as a function of x, we need to understand the concept of a function and how it is graphed.
A function is a relation between two sets of numbers, where each input value (x) is associated with only one output value (y). In other words, for a graph to represent y as a function of x, every value of x must have a unique corresponding value of y.
To identify whether a graph represents y as a function of x, we can use the vertical line test. This test involves drawing a vertical line through the graph. If the vertical line intersects the graph at only one point for every x-value, then the graph represents y as a function of x. On the other hand, if the vertical line intersects the graph at two or more points for any x-value, then the graph does not represent y as a function of x.
So, to determine which graph represents y as a function of x, you should visually examine each graph and apply the vertical line test. If you can draw a vertical line that intersects the graph at only one point for every x-value, then that graph represents y as a function of x.
