Answer:
A. Only graph B and D
Explanation:
Hi, to answer this question we have to analyze the options given:
A function has only one output value (y) for each input value.(x)
In other words, If we draw a vertical line (anywhere on the graph) that intersects the graph in two points or more, then the graph does not represent a function because that x value has more than one output(y).
So, the correct option is:
A. Only graph B and D
