Math Problem Statement

Explain whether the graph represents a linear function.

Solution

The given graph does not represent a linear function because the curve is not a straight line. A linear function has a constant rate of change (slope), which means its graph must form a straight line.

In this graph:

  • The curve is clearly nonlinear as it bends downward, showing a varying slope.

Let me know if you'd like a deeper explanation of the criteria for linearity!

Tip:

When checking for linearity, observe the graph for straightness and test a few points to see if the slope remains constant between them!
