Quizz

1. Chemistry – Cooling of a Liquid

A cup of tea is initially at 90°C and cools down in a room with a constant temperature of 20°C. The temperature decreases rapidly at first and then more slowly over time.[br][br]Which type of function best models this process?

Exponential decay function Linear function Sinusoidal function Quadratic function

2. Biology – Population Growth

A bacteria culture starts with 200 bacteria. Every hour, the number of bacteria doubles under ideal laboratory conditions.[br][br]Which function could model the number of bacteria after xxx hours?

[math]\text{f(x)=x^2+200}[/math] [math]\text{f(x)=200⋅2^x}[/math] f(x)=200−x f(x)=200+2x

3. Physics – Height of a Thrown Ball

A ball is thrown upward from the ground. Its height increases, reaches a maximum point, and then decreases back to the ground.[br][br]Which function best models the height of the ball over time?

Quadratic function Exponential growth function Linear function Constant function

4. Geography – Tides at the Seaside

The water level at a seaside location rises and falls repeatedly during the day due to tides.[br][br]Which type of function best models the water level over time?

Quadratic function Logarithmic function Exponential function Sinusoidal function

5. History – Spread of a Historical Innovation

The use of printing presses in Europe increased slowly at first, then very rapidly, and finally stabilized as most cities adopted the technology.[br][br]Which type of graph best represents this evolution?

Constant function Logistic (S-shaped) function Periodic function Linear increasing function
