A pebble is dropped from a bridge into a river. The height of the pebble above the water after it has been released is modelled by the function \( h ( t ) = - 5 t ^ { 2 } + 45 \) , where \( t \) is the time in seconds. a. Graph the function for reasonable value of \( t \) . b. Write the domain and range in set notation.
