Answer:
C.) The ball was thrown from a height of 3 feet
Explanation:
In the standard form of a quadratic function, f(x) = ax² + bx + c,
c is the constant term (also known as the y-intercept of the parabola)
In this situation, the ball is thrown up into the air and the flight path will be in the shape of a parabola
The equation y = -16t² + 40t + 3 has a y-intercept of 3, meaning the flight path began at 3 feet above the ground, as you can imagine by looking at the graph of the equation, below. The y-intercept is at (0,3)
