Graph the relation and determine if it is a function. Explain why it is or isn’t.
{(4, -2), (4, -4), (1, 2), (1, 5), (1, -4)}
The graph of the relation can be represented as points in a coordinate plane.
The given points are: (4, -2), (4, -4), (1, 2), (1, 5), and (1, -4).
To determine if it is a function, we need to check if each x-value has only one corresponding y-value.
In this case, we have multiple y-values for the x-values of 4 and 1.
For x = 4, we have y = -2 and y = -4.
For x = 1, we have y = 2, y = 5, and y = -4.
Since there are multiple y-values for both x = 4 and x = 1, the relation is not a function.
