The height, h metres, of a particle at time, t seconds is given by the function:
h=(14-t)(t-2).
how would you work that out?

It depends on what you are asked to do. See explanation.

Step-by-step explanation:

The height, h metres, of a particle at time, t seconds is given by the function:

h=(14-t)(t-2).

This means that after a given time, we can use this function to find the height of the particle.

For instance after 3 seconds, the height of the particle will be:

This implies that:

So after 3 seconds the height of the particle is 11 meters.
