Question

is this a function? graph of a curve yes no

Explanation:

Step1: Recall Function Definition

A function is a relation where each input (x - value) has exactly one output (y - value). We use the vertical line test: if any vertical line intersects the graph more than once, it's not a function.

Step2: Apply Vertical Line Test

For the given graph, if we draw a vertical line (e.g., at x = 4, 5, 6, etc.), it will intersect the graph at two points. This means there are x - values with more than one y - value.

Answer:

No
