A basketball is thrown, and its height above ground is represented by the function f(x)=-3x^2+10x+4. At the same time, a drone t
akes off from the ground, and its height above ground is represented by the function f(x)=3^x-1. The heights above the ground of the ball and the drone are shown in the graph below.
If x represents time in seconds, approximately how many seconds does it take for the drone to be higher than the basketball?
