To graph the relationship
, start by identifying the shape and key features of the parabola. This equation is a quadratic in
and opens downwards because the coefficient of
is negative. The vertex, which is the highest point, can be found using the formula
, where
and
. Plugging in the values gives
; substituting back into the equation gives
. Plotting the vertex and a few points around it will yield a nice curve, revealing how height varies with time!
Another fun way to explore this equation is to consider how it might represent a projectile’s motion, like throwing a ball. As time increases, the height climbs to a maximum of 25 units at 5 seconds, after which gravity causes the height to decrease. If you set
, you can find when the ball hits the ground by solving
, leading to
. Therefore, the ball returns to the ground at
and
. This real-life analogy of projectile motion is a great way to connect math with the physics of everyday phenomena!
