I need to know how to find the domain and range from a word problem please. For example: A ball is thrown into the air at different heights. F(t) represents the height at which the ball is currentlyat and t represents the time since the ball was thrown. The function F(t) models this belowf(t) =-2t^2 + 4t + 1What is a reasonable domain and range for this scenario?

The height f(t) is modelled as;


f(t)=-2t^2+4t+1

Where t is the time since the ball was thrown.

Usually, the domain of a quadratic function is;


-\inftybut in this case, we plot the graph of the function as;<p>And thus, it is not possible to record a negative time, then the <strong>reasonable domain for the scenario is;</strong></p>[tex]0\leq x\leq\mathring{2.225}

Similarly, the reasonable range of the scenario is;
