Step 1
9t^2$ We need to express $y$ as a function of $x$, i.e., $y = f(x)$. To do this, we will solve the equation for $x(t)$ for $t$ and substitute it into the equation for $y(t)$. Show more…

A bullet follows the trajectory c(t) = (90t, 100t - 16t^2). Show that the path traced by the bullet is a parabola by eliminating the parameter. The path traced by the bullet follows the trajectory c(t) = (90t, 100t - 16t^2) = (x, y). Therefore, we use the following parametric equations to describe the trajectory. We wish to show that the path is a parabola by eliminating the parameter: The easiest way to eliminate the parameter is to solve for t in terms of x and substitute that value into the equation that describes y. Solve for t in terms of x.
