A school wishes to form three sides of a rectangular playground using 240 meters of fencing. The playground borders the school building, so the fourth side does not need fencing.

As shown below, one of the sides has length x (in meters).

Find a function that gives the area A(x) of the playground (in square meters) in terms of x.

Melissa has 440 meters of fencing and wishes to form three sides of a rectangular field. The fourth side borders a river and will not need fencing. 

As shown below, one of the sides has length x (in meters).

Find a function that gives the area A(x) of the field (in square meters) in terms of x. 

Below is the graph of a polynomical function with real coefficients. All local extrema of the function are shown in the graph. 

What is the sign of the function's leading coefficient?

Below is the graph of a polynomical function with real coefficients. All local extrema of the function are shown in the graph.
