Give an example of a function from everyday life. _____________ depends on ___________, so ________ is a function of ___________. Explain.

Solution

Speed depends on distance travelled and time taken. so, speed (s) is function of disatnce.

A bicycle covers a distance in 20 seconds. The speed of the bicycle is given by

s = d/20 = 0.05 d

where

s = speed (in ms¹, or meters per second, m/s)

d = distance (in meters, m)

If the distance covered by the bike is 10 m, then the speed is s=0.05×10=0.5 m/s.

If d increases, the speed goes up.

If d decreases, the speed goes down.

We say speed is a function of distance (when time is constant). We get only one value of s for each value of d.
