Use the equation y = ax^2 + bx + c where x is the horizontal distance a baseball has traveled and y is the height of the ball at the given distance.
1)Are some values of y unreasonable?
2)How is this information important for choosing a window for the graph?
3) With respect to the quadratic polynomial, the value of x has a name. what is it called?
I assume some values of y would be unreasonable because you couldn't hit the ball that high. Am I on the right track?
On the graph the distance when the ball landed would be the x-intercept, but I do not know what the value of x is called with respect to the quadratic polynomial. Would it be a root? Please help.
