Question

a. yes
b. no

Explanation:

The graph shown is a parabola opening upwards with vertex on the y - axis. A function is a relation where each input (x - value) has exactly one output (y - value). For this parabola (a quadratic function), for every x, there is only one y. Also, if we apply the vertical line test (a vertical line drawn anywhere on the graph intersects the graph at most once), this graph passes the vertical line test. So, it represents a function, and the answer should be "Yes".

Answer:

A. Yes
