Question

when using a quadratic equation in the form y = ax² + bx + c to model the height of a projectile (y) over time (x), which of the following is always represented by the constant term? the initial height of the projectile the initial velocity of the projectile the time at which the projectile hits the ground the maximum height of the projectile

Explanation:

When \(x = 0\) (at the start, initial - time), \(y=a(0)^2 + b(0)+c=c\). Since \(y\) represents height and \(x = 0\) is the initial time, \(c\) represents the initial height of the projectile.

Answer:

the initial height of the projectile
