Question

is this graph an example of a nonlinear function?

no
yes

Explanation:

Identify the shape of the graph

$$ \text{The graph is a parabola (U-shaped curve).} $$

Determine if the graph represents a linear function

$$ \text{A linear function must form a straight line, which has a constant rate of change.} $$

Classify the function as linear or nonlinear

$$ \text{Since the graph is a curve and not a straight line, it is a nonlinear function.} $$

Answer:

• No
• Yes (Correct answer)
