Point A represents the height the ball is thrown from.
What is y-intercept of a parabola?
The y-intercept of a parabola is the point where the graph intersects the y-axis.
For a quadratic equation y = ax² + bx + c, the y-intercept occurs when x = 0.
To find the y-intercept, set x = 0 in the equation:
y = a(0)² + b(0) + c = c
So, the y-intercept is the point (0, c) on the graph of the parabola.
It is the constant term in a quadratic equation.
It context of the ball, it represents the initial height of the ball. That's the height of the ball when time,t = 0.
Which means even when the time has not started reading the ball is already at point A.
so, point A represents the height the ball is thrown from.
