Why is a function with two separate linear sections considered nonlinear?

• Because it has a constant rate of change.

• Because it can be graphed with one straight line.

• Because it does not form a single straight line.

• Because it has multiple outputs for a single input.

What is a key difference between linear and nonlinear functions?

• Nonlinear functions follow the equation y = mx + b.

• Linear functions have a variable rate of change.

• Nonlinear functions have a constant rate of change.

• Linear functions form a straight line on a graph.
