A stunt driver launches a car off a ramp at a cliff's edge. [br]The height of the car above the ground (in meters) as a function of the horizontal distance traveled x (in meters) is modeled by the quadratic function: [math]f\left(x\right)=-0.05x^2+0.8x+20[/math]
Find the maximum height reached by the car
Find the horizontal distance it travels before hitting the ground (f(x) = 0).
