Is the time it takes you to run a 100-meter race a function of the speed you run? Explain.
Yes, the time it takes to run a 100-meter race is a function of the speed you run. A function is a relationship between two variables, where each input value (speed) corresponds to a unique output value (time).
In the case of running a 100-meter race, the speed at which you run directly affects the time it takes to complete the race. The faster you run, the shorter the time it takes to finish. Similarly, if you run slower, it will take a longer time to complete the race.
Therefore, there is a clear cause-and-effect relationship between the speed at which you run and the time it takes to finish a 100-meter race, making it a function.
