Question

A car stops at a red light for 30 seconds what function is this
Linear
Constant
Quadratic

Answer 1

The situation you described, where a car stops at a red light for 30 seconds, can be modeled by a **constant function**. A constant function has the same value over a specified interval—in this case, the car's speed is constant at zero (it is not moving) for 30 seconds.

A linear function would be characterized by a changing value (like speed increasing or decreasing), and a quadratic function involves a variable raised to the second power, typically creating a parabolic shape, which does not apply in this scenario.

So, the correct answer is **Constant**.
