Question

What's the correct answer

Answer 1

Food for (your) thought:
1. Is this the graph of a straight line?
2. What does a proportional relationship look like?
3. If a graph passes through the origin, does that mean that the function it represents is proportional?

If you answer these questions correctly, you'll be in a better position to elimiinate the incorrect answer choices.

Answer 2

C, the graph is not a straight line, meaning that for every x value, a definite y value is not present. The graph is an exponential graph, meaning that for every x value, the y value is related to the power of x.
