Answer:
The input x = 1 has many outputs.
The graph is a vertical line.
Step-by-step explanation:
Hi there!
A function is defined as a relation that only gives one output for every given input. For every x-value, there is only one y-value.
Because the x-value of 1 gives us an infinite number of y-values, this is therefore not a function.
More generally, no vertical line is a function for this reason.
I hope this helps!
